Similar Triangles

Front

Matching angles are called

Back

Corresponding Angles

Front

Sides in similar figures must be proportional. True or False?

Back

True

Front

Front

If two shapes are similar, solve for X: 2 ft, 3 ft, 4 ft, 6 ft.

Back

2 ft

Front

What is the definition of similar triangles?

Back

Triangles that have the same shape but may have different sizes; their corresponding angles are equal and their corresponding sides are proportional.

Front

What is the ratio of corresponding sides in similar triangles?

Back

The ratio is constant and equal for all pairs of corresponding sides.

Front

What are corresponding sides?

Back

Sides in two or more shapes that are in the same relative position.

Front

What is the Angle-Angle (AA) similarity postulate?

Back

If two angles of one triangle are equal to two angles of another triangle, the triangles are similar.

Front

If triangle ABC is similar to triangle DEF, what can be said about their angles?

Back

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

Front

If the sides of triangle ABC are 3, 4, and 5, and triangle DEF is similar to ABC with a scale factor of 2, what are the lengths of the sides of triangle DEF?

Back

6, 8, and 10.
