Angle Pairs Practice

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside the two lines it intersects. They are equal when the lines are parallel.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal in measure.

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 when the lines are parallel.

Front

What is a linear pair of angles?

Back

A linear pair of angles consists of two adjacent angles that form a straight line. The sum of the angles in a linear pair is always 180 degrees.

Front

Can you give an example of a pair of vertical angles?

Back

An example of a pair of vertical angles is ∠1 and ∠4 when two lines intersect, creating two pairs of opposite angles.

Front

What is the relationship between alternate interior angles and parallel lines?

Back

If two lines are parallel, then alternate interior angles are equal. Conversely, if alternate interior angles are equal, the lines are parallel.

Front

What is the sum of the angles in a linear pair?

Back

The sum of the angles in a linear pair is always 180 degrees.

Front

How do you identify corresponding angles?

Back

Corresponding angles can be identified as angles that occupy the same relative position at each intersection where a straight line crosses two others.

Front

What is the significance of vertical angles in geometry?

Back

Vertical angles are significant because they are always equal, which can be used to solve for unknown angle measures in geometric problems.

Front

What is the transversal in relation to angle pairs?

Back

A transversal is a line that intersects two or more lines at different points, creating various angle pairs such as alternate interior, corresponding, and vertical angles.
