Corresponding Sides and 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 similar figures.

Front

If two angles are corresponding, what can we say about their measures?

Back

If two angles are corresponding, their measures are equal.

Front

What is a transversal?

Back

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

Front

How do you identify corresponding angles in a diagram?

Back

Look for angles that are in the same relative position at each intersection of the transversal with the parallel lines.

Front

What is the relationship between corresponding sides of similar triangles?

Back

The corresponding sides of similar triangles are proportional to each other.

Back

The angle that corresponds to angle A in another triangle is the angle that is in the same position relative to the corresponding sides.

Front

What is the significance of corresponding angles in parallel lines?

Back

Corresponding angles formed by a transversal intersecting parallel lines are equal, which helps in proving lines are parallel.

Front

If angle B corresponds to angle Y, what can we conclude?

Back

Angle B and angle Y are equal in measure.
