In a technical drawing, a hexagon bordered number typically indicates a specific type of dimension or annotation related to the geometry of the object being represented. It often signifies a reference or a standard that must be adhered to, such as tolerances or specifications. The hexagonal shape can also denote a special note or requirement that is crucial for the interpretation of the drawing, distinguishing it from other annotations.

By the fact that they are congruent means that they are exactly the angle size, the same length of sides and the same area.

Similarity means that only the ANGLES are the SAME.

Similar polygons have the same size angles, but the side lengths are proportionally different, thereby the area is different.

Congruent polygons have the same size angles, the side lengths, thereby the area is the same.

In mathematics , NO!!!!

e.g. two triangles can be SIMILAR. That is they have the same angles, but the sides a proportionally lomger/shorter. Thereby the areas are different.

NB Do NOT confuse SIMILARITY with CONGRUENCY.

Congruency means the triangles have the same angles AND the same side lengths. . Thereby the same area.

In a regular octagon, all sides are equal in length, and all interior angles are the same (each measuring 135 degrees). However, in an irregular octagon, the sides can vary in length, and the angles can differ as well. Therefore, whether all sides are the same depends on whether the octagon is regular or irregular.

Three-dimensional art encompasses various forms, including sculpture, installation art, and ceramics. Sculptures can be made from materials like stone, metal, or wood, ranging from realistic figures to abstract forms. Installation art often combines various media and engages with the surrounding space, inviting viewer interaction. Ceramics involves creating functional or decorative objects using clay, often incorporating glazing and firing techniques.

The minimum and maximum boom angles of a crane depend on the specific type and model of the crane, as well as the operational requirements. Generally, the minimum boom angle is close to horizontal (0 degrees) for maximum outreach, while the maximum boom angle is typically around 80 to 90 degrees for lifting vertically. Always refer to the manufacturer's specifications and guidelines for precise values. Properly understanding these angles is crucial for safe and efficient crane operation.

A track oval refers to a circular or elliptical running track commonly used in athletics for races and training. It typically features a surface that is suitable for runners, with a standard length of 400 meters for the outer lane. Track ovals are designed for various events, including sprints, middle-distance races, and relays, and often include lanes marked for individual runners. Additionally, the design allows for efficient crowd viewing and facilitates the organization of competitions.

The answer regarding a mural with an area of 18 square meters indicates that the total surface area covered by the mural is 18 m². This area measurement can help determine the amount of paint or materials needed for the mural or its dimensions if the length and width are known. For instance, a mural could be 6 meters long and 3 meters high, or any other combination of length and width that multiplies to 18 m².

If a statement is true, then its negation is false. The negation of a statement is essentially the opposite of that statement; it asserts that the original statement is not true. Therefore, if the original statement holds true, the negation cannot hold true simultaneously.

Concentric circles can be found in various places and objects, such as tree rings, which represent growth layers, and ripples in water created by a dropped stone. Other examples include target designs in archery, where circles denote scoring zones, and the rings of a vinyl record. Additionally, architectural features like domes and circular windows often exhibit concentric circle patterns.

Yes, Oblong is the name of a rectangle who's length is greater than it's width.

A tie connects two notes on the same line or space, allowing them to be played as a single, sustained note. It indicates that the second note should not be rearticulated but rather held for the duration of both notes' values. Ties are often used to extend the duration of a note beyond its standard time value in musical notation.

A figure composed of two line segments that share the same endpoint is called an "angle." The point where the two segments meet is known as the vertex of the angle, while the segments themselves are referred to as the "sides" of the angle. Angles can be measured in degrees or radians and are fundamental in geometry and trigonometry.

A piece of wire twisted to form a circle is commonly referred to as a wire loop or wire ring. This simple shape can be utilized in various applications, such as jewelry making, crafting, or as a component in mechanical assemblies. The twisted design can enhance its structural integrity and aesthetic appeal, depending on the thickness and type of wire used.

The kidney's distinctive shape is primarily a result of its functional requirements and anatomical positioning within the body. The concave side, known as the hilum, allows for the entry and exit of blood vessels, nerves, and the ureter, facilitating efficient waste filtration and urine transport. Its shape also maximizes surface area for filtration while accommodating the limited space in the abdominal cavity. Additionally, the kidney's morphology helps to optimize blood flow and filtration efficiency.

To find the length when the area is known, you can use the formula for the area of the shape in question. For example, for a rectangle, the area ( A ) is calculated as ( A = \text{length} \times \text{width} ). Rearranging this formula, the length can be found by dividing the area by the width: ( \text{length} = \frac{A}{\text{width}} ). For other shapes, similar rearrangements of their area formulas can be applied.

The electron geometry of CBr4 (carbon tetrabromide) is tetrahedral. This is due to the central carbon atom being bonded to four bromine atoms, which results in four regions of electron density around the carbon. The arrangement minimizes repulsion between these regions, leading to the tetrahedral shape.

To find the area of a rectangle with a given perimeter, we first use the formula for the perimeter, which is ( P = 2(l + w) ), where ( l ) is the length and ( w ) is the width. Given the perimeter of 42.5 cm, we have ( l + w = 21.25 ) cm. However, without specific values for length and width, we cannot determine the exact area, as it depends on the dimensions chosen. The area can be calculated as ( A = l \times w ), but multiple combinations of ( l ) and ( w ) can yield the same perimeter but different areas.

The circle with an exclamation mark inside it typically signifies a warning or alert. It indicates that there is important information or a potential issue that needs attention. This symbol is commonly used in various contexts, such as on electronic devices, applications, or warning signs, to prompt users to act or be cautious.

The perimeter is the total length of the boundaries of a two-dimensional shape, calculated by adding the lengths of all its sides. In contrast, surface area refers to the total area of all the surfaces of a three-dimensional object, representing the amount of space that the surface of the object occupies. Essentially, perimeter deals with length, while surface area deals with area.

In a pentagon, the sum of the interior angles is 540 degrees. Since each right angle is 90 degrees, the maximum number of right angles that can fit within this total is 4, which would account for 360 degrees. The fifth angle would then be 180 degrees, which is not possible in a polygon. Therefore, the largest number of right angles possible in a pentagon is 4.

The cutting angle for a cable tray is typically determined using the formula: Cutting Angle (θ) = arctan (Rise/Run), where "Rise" is the vertical height the tray needs to ascend and "Run" is the horizontal distance. This angle ensures that the cable tray is angled appropriately for installation and support. It's important to measure accurately to maintain structural integrity and functionality.

To calculate the circumference of a pipe, you can use the formula ( C = \pi \times d ), where ( d ) is the diameter. For a 25 mm pipe, the diameter is 25 mm. Therefore, the circumference is approximately ( C = \pi \times 25 \approx 78.54 ) mm, using ( \pi \approx 3.14 ).

If you split a square into two triangles, you create two right triangles by drawing a diagonal line from one corner of the square to the opposite corner. Each triangle will have half the area of the original square. The two triangles will be congruent, having the same shape and size, and their combined area will still equal the area of the square. This geometric transformation illustrates the concept of dividing shapes while preserving their area.
