# How are corresponding angles of similar figures related?

The angles of similar figures are equal. That is what gives them the same shape.

The sides of similar figures are in equal ratios.

When two shapes are similar, it means that their angles are equal and their sides are in the same ratio.

In the example below, the corresponding angles are equal, but all of the sides are in equal proportions.

Say that angle A is 30˚. Then, angle D is also 30˚. If angle B is 50˚, angle E must also be 50˚.

Angles A and D are corresponding angles and are equal.

Angles B and E are corresponding angles and are equal.

Angles C and F are corresponding angles and are equal.

The lengths of the sides are in the ratio. 1 :2

Side AB = 10, so side DE = 20.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- I have 6 faces, 8 vertices, and 12 edges. Which figure am l?
- Using the following figure, identify relationship of the angles or sum of the angles?
- Angles A and B are complementary. If measurement of angle #A = 3x-8# and measurement of angle #B = 5x+10#, what is #x#?
- The sum of the measures of two complementary angles is 90degrees°. If one angle measures 9 degrees° more than twice the measure of the other, find the measure of the smaller angle?
