Angle Pair Relationships

Front

What are angle pair relationships?

Back

Angle pair relationships refer to the relationships between angles formed when two lines intersect or when a line crosses two parallel lines. These relationships include complementary, supplementary, vertical, and corresponding angles.

Front

Define complementary angles.

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

Define supplementary angles.

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What are vertical angles?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others. They are equal when the lines are parallel.

Front

What are alternate interior angles?

Back

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

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two lines and on opposite sides of a transversal. They are equal when the lines are parallel.

Front

What are same side interior angles?

Back

Same side interior angles are pairs of angles that lie between two lines and on the same side of a transversal. They are supplementary when the lines are parallel.

Front

What are same side exterior angles?

Back

Same side exterior angles are pairs of angles that lie outside two lines and on the same side of a transversal. They are supplementary when the lines are parallel.

Front

If two angles are complementary and one angle measures 30 degrees, what is the measure of the other angle?

Back

The other angle measures 60 degrees.
