## What is it called when a polygon has all angles congruent?

The name of a polygon describes the number of sides. A polygon which has all sides mutually congruent and all angles mutually congruent is called a regular polygon.

## What is needed to prove that two polygons are similar?

Similar polygons: For two polygons to be similar, both of the following must be true: Corresponding angles are congruent. Corresponding sides are proportional.

## Are the polygons similar if they are write?

ANSWER: No; the angles are not the same, so the polygons do not have the same shape, so there are no similarity transformations between the figures. List all pairs of congruent angles, and write a proportion that relates the corresponding sides for each pair of similar polygons.

## Are the polygons similar if they are write a similarity Statement 110?

yes you are correct!

m/40

## How do you write a similarity statement?

To write a similarity statement, start by identifying and drawing the similar shapes. See where the equal angles are and draw the shapes accordingly. Label all the angles. Write down all the congruent angles (for example, angle ABC is congruent to angle DEF, angle BCA is congruent to angle EFD, etc.).

## How do you find the value of each variable in similar polygons?

When polygons are similar, the scale factor can be used to find the values of variables. Determine the scale factor. Then set up a proportion and solve for the unknown variable. solve for the unknown variable.

## How do you find scale factor?

To find the scale factor, locate two corresponding sides, one on each figure. Write the ratio of one length to the other to find the scale factor from one figure to the other. In this example, the scale factor from the blue figure to the red figure is 1.6 : 3.2, or 1 : 2.

## What does scale factor mean in maths?

A scale factor in math is the ratio between corresponding measurements of an object and a representation of that object.

## How do you enlarge a shape with a scale factor of 2?

Locate the Centre of Enlargement, then draw Ray Lines from the centre of enlargement through the vertices of the shape. If a shape is being enlarged by a scale factor of 2, the distance from the centre of enlargement to each vertex will be twice the size. The size of the shape will also be twice the size.
