Similar Figures

Front

What are similar figures?

Back

Similar figures are shapes that have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are proportional.

Front

Are all angles in similar figures congruent?

Back

True

Front

What are corresponding sides in similar figures?

Back

Corresponding sides are the sides in the same position on similar figures that maintain a proportional relationship.

Front

Which statement is NOT true about similar figures?

Back

B) Similar figures always have the same size.

Front

What is the relationship between corresponding angles in similar figures?

Back

Corresponding angles in similar figures are always equal.

Front

If ΔABC ∼ ΔDEF, what can we say about the angles?

Back

Angle A = Angle D, Angle B = Angle E, Angle C = Angle F.

Front

What is the ratio of the corresponding sides of similar figures?

Back

The ratio of the corresponding sides of similar figures is constant and is called the scale factor.

Front

How do you find the scale factor between two similar figures?

Back

To find the scale factor, divide the length of a side of one figure by the length of the corresponding side of the other figure.

Front

If two triangles are similar, how can you find a missing side length?

Back

You can set up a proportion using the lengths of the corresponding sides and solve for the missing length.

Front

What does it mean for two figures to be congruent?

Back

Congruent figures are identical in shape and size, meaning all corresponding sides and angles are equal.
