Corresponding Sides & Angles

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on different parallel lines cut by a transversal. They are equal in measure.

Front

What are corresponding sides?

Back

Corresponding sides are sides of two or more geometric figures that are in the same relative position. They are proportional in length when the figures are similar.

Front

If two triangles are similar, what can be said about their corresponding angles?

Back

The corresponding angles of similar triangles are equal.

Front

If two triangles are similar, what can be said about their corresponding sides?

Back

The corresponding sides of similar triangles are in proportion.

Front

What is the relationship between corresponding angles and parallel lines?

Back

When a transversal crosses parallel lines, the corresponding angles formed are equal.

Front

How do you identify corresponding sides in similar triangles?

Back

Corresponding sides can be identified by their position relative to the corresponding angles.

Front

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

Back

The AA similarity postulate states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What is the Side-Angle-Side (SAS) similarity theorem?

Back

The SAS similarity theorem states that if an angle of one triangle is equal to an angle of another triangle and the sides including those angles are in proportion, then the triangles are similar.

Front

What is the Side-Side-Side (SSS) similarity theorem?

Back

The SSS similarity theorem states that if the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

What is a transversal in geometry?

Back

A transversal is a line that intersects two or more lines at different points.
