Corresponding Angles and Sides - Bell Ringer

Front

What are corresponding angles?

Back

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

Front

What are corresponding sides in similar triangles?

Back

Corresponding sides in similar triangles are the sides that are in the same relative position in each triangle. The lengths of corresponding sides are proportional.

Front

How do you identify corresponding sides?

Back

To identify corresponding sides, look for the sides that are in the same position relative to the angles in similar figures or triangles.

Front

What is the relationship between corresponding angles and parallel lines?

Back

When two parallel lines are cut by a transversal, the corresponding angles formed are equal.

Front

What is a transversal?

Back

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

Front

What is the scale factor in similar triangles?

Back

The scale factor is the ratio of the lengths of two corresponding sides of similar triangles.

Front

If angle D corresponds to which angle?

Back

Angle D corresponds to angle S.

Front

If side EF corresponds to which side?

Back

Side EF corresponds to side TU.

Front

What is the scale factor if SU is 4 and its corresponding side is 2?

Back

The scale factor is 2 (4 divided by 2).

Front

How do you find the corresponding angle to a given angle?

Back

To find the corresponding angle, identify the position of the given angle relative to the transversal and parallel lines, then find the angle in the same position on the other line.
