How you can use a ratio to enlarge or reduce a figure.?
Suppose the ratio is R.Select a side of the first figure. Suppose its length is L1. Draw a line that is L1*R units long.At the end of the line, draw an angle congruent to that on the first figure.Suppose the second side of the first figure is L2. In the second figure, draw a line that is L2*R units long.Continue in the same way all round the figure.
What will a scale factor greater than i do to a figure?
A scale factor greater than 1 will enlarge a figure, increasing its dimensions proportionally. Each point of the figure will move away from the origin (or a designated center of enlargement) by a factor equal to the scale factor. As a result, the overall shape of the figure remains the same, but its size increases. This transformation preserves the figure's proportions and angles.
When you enlarge something on a photocopy machine is that image a dilation?
Yes, when you enlarge an image on a photocopy machine, it can be considered a dilation. Dilation in geometry refers to the transformation that changes the size of a figure while maintaining its shape and proportions. In the case of photocopying, the enlarged image retains the same shape and relative dimensions as the original, making it an example of dilation.
Why are dilations similar to scale drawings?
Dilations are similar to scale drawings because both involve resizing an object while maintaining its proportional dimensions. In a dilation, each point of the original figure is moved away from a center point by a scale factor, resulting in a similar figure that retains the same shape. Similarly, scale drawings use a specific ratio to enlarge or reduce the size of an object, ensuring that all dimensions remain proportional. Thus, both processes create figures that are geometrically similar.

When you enlarge or reduce a figure what are the features that stay the same?
the angles stay the same but the lenght of the sides change.
Why do the angles stay the same if you enlarge or reduce a figure?
Because the figures are said to be similar to each other and retain the same angles

What is the eidograph?
The eidograph is a mechanical drawing instrument invented in 1821 by the Scottish mathematician William Wallace, designed to copy, enlarge, or reduce plane drawings with precise geometric accuracy. It belongs to the same family of tools as the pantograph, but refines the idea in one key way: instead of pivoting from a corner, Wallace placed the fixed fulcrum at the center of the linkage. The instrument is built from three graduated bars. A central beam rests on a single weighted pivot pin, while two lighter side-bars extend from equal-sized pulleys mounted at its ends. A steel band inside the beam links the pulleys so the two side-bars always turn in exact step with one another. A tracing point at the tip of one side-bar follows the outline of an original drawing; a pencil at the tip of the other, positioned diagonally opposite, reproduces it automatically. Because the fulcrum sits between the two points, the copy comes out rotated 180° from the original, scaled by whatever ratio the sliding beam is set to. Before photographic reproduction existed, the eidograph was a favorite of draughtsmen, surveyors, and mapmakers needing fast, faithful copies at a different scale.
What is a similar plane figure?
It is a figure that is the same as another figure in the plane. A square is the same plane figure as another square, but a cube is same the same plane figure even tho it is made up of 6 squares.
How do you deduct a minus figure from a plus figure?
It's the same as adding the same figure without the minus figure. '+' minus '-' = '+'
What does the word enlarge mean?
The word "enlarge" means to make larger, or to become larger. A company may enlarge its warehouse to store more goods, or an infection could cause a lymph node in the body to enlarge.When used for images, the word enlarge means to "blow up" or increase in scale so as to display more detail. A photographic enlargement is the same photo in a larger size.
In maths how do you enlarge a shape by the scale factor of 1?
if you multiply all the points by one you get the same points so the shape stays the same.
