### What is the name of the figure that has three sides and one 90 degree angle?

A right(-angled) triangle

### What is an equal angled figure?

An equal angled figure is a shape in which all the angles are the same: Examples - square (four 90-deg angles), rectangle (four 90-deg angles), equilateral triangle (three 60-deg angles), etc.

### Is there such thing as a right angled triangle?

Yes, there is such thing as a right-angled triangle. The measure of the adjacent and opposite form together to create a 90 degree angle. That means that the measure of the hypotenuse and adjacent must be 45 degrees and the hypotenuse and opposite measures to 45 degrees.

### Is an abTuse triangle a eight triangle?

octogon * * * * * An obtuse angled triangle is a plane figure which is bounded by three straight sides, such that one of its angles is in the range (90, 180) degrees. By definition, all triangles can have only three sides and three vertices, so an eight triangle cannot exist.

### What is a 11 angled and sided polygon?

A nonagon or enneagon. Another answer: An eleven sided figure is also called an hendecagon.

### What does a geometric figure look like with 1 right angle and 2 acute angles?

A right angled triangle.

### What is the name given to three whole numbers that can be the three sides of a right angled triangle?

Pythagorean triple

### How many lines of symmetry does a acute triangle triangle?

3 lines * * * * * None if it is acute angled scalene One if it is acute angled isosceles and Three if it is equilateral.

### If you have three sizes one of your angels are 90 degrees what are you?

Right angled triangle

### What is a four-sided figure with one pair of parallel lines and two right angle?

it is a right angled trapezium

### Is a two angled triangle impossible?

By definition a triangle is a polygon with three sides and three angles, so yes. Tri (three) angles.

### What polygon and three angles and three sides and one of the angles is greater than 90 degrees?

An obtuse angled triangle.

### What triangle have three angles with measurement greater than zero called?

If a three-sided figure (triangle) has one angle that is zero, then all angles will be zero and the three sides will be coincident, that is, they will occupy the same space and will, therefore form a single line. Such a figure would not be referred to as a triangle, and would have little practical value in trigonometry (the study of triangles). Therefore, every triangle has three angles greater than zero degrees, whether it be… Read More

### Is a right angled and a eqilateral triangle the same?

Absolutely not, not ever, nohow! An equilateral triangle has three angles of 60 degrees, a right-angled triangle must have one of 90 degrees.

### A geometric figure having three ling segments for sides?

A triangle is a geometric figure that is made of three line segments. It is a closed figure and has three angles.

### How many diagonals with a three side figure?

Diagonals connect corners of a figure. If you try to connect two corners of a three sided figure, the lines you draw will exactly mimic the sides of the figure. Because of this, a three sided figure has no diagonals.

### Does a triangle have 3 obtuse angles?

cannot because a triangle has to have 180 degrees i.e. obtuse angled triangle has one obtuse angle acute angled triangle has three acute angles

### What is the precise name of a three sided shape with all angles acute?

An acute angled triangle.

### How many sides does a right angled triangle?

ALL triangles have three sides and three angles. The three angles always add up to 180 degrees. A right angled triangle has one 90 degree right angle and two smaller angles. No triangle can have any parallel sides. An equilateral triangle has three equal sides and therefore three equal 60 degree angles.

### Is a square a three dimensional figure?

A square is not a three dimensional figure unless it is in the form of a cube.

### What is a four sided three dimensional figure?

A pyramid is a four-sided, three-dimensional figure.

### How do you match a three-dimensional figure with its net?

match a three dimentional figure with net

### What does the word tri in triangle stand for?

tri means three as in a 'tri'cycle a three wheeled bike 'tri'angle as in three angled shape a triangle has three angles so they used tri because it means three

### How do you find the hypotenuse of a non right triangle?

By definition, the hypotenuse is the side opposite the right angle in a right angled triangle. Therefore, a hypotenuse does not exist as one of the three sides in a non-right angled triangle.

### What is a three dimensional figure that has faces with more than one dimensional figure?

All three dimensional figures have more faces than a one dimensional figure. There are an infinite number of one dimensional points on a three dimensional figure

### What type of triangle has an angle that measures 120 degrees?

An obtuse angled triangle. An obtuse angled triangle. An obtuse angled triangle. An obtuse angled triangle.

### Can a right triangle have three acute angles and three equal sides?

No, a right angled triangle cannot have three acute angles because an acute angle is less than 90 degrees and a right angled triangle has one angle of exactly 90 degrees (which is what right angled means, equal to 90 degrees). Also, because the triangle has a right angle (of 90 degrees) it cannot have three equal sides; it can have two equal sides but the side opposite to the right angle (the hypotenuse) will… Read More
