Angles and Triangles

Front

What is the definition of supplementary angles?

Back

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

Front

If angle A is 120 degrees, what is the measure of its supplementary angle B?

Back

60 degrees.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that are on opposite sides of a transversal and outside the two lines.

Front

If two parallel lines are cut by a transversal, what can be said about corresponding angles?

Back

Corresponding angles are equal.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

What is the definition of complementary angles?

Back

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

Front

If angle C is 30 degrees, what is the measure of its complementary angle D?

Back

60 degrees.

Front

What is the relationship between the angles formed when two parallel lines are cut by a transversal?

Back

The angles formed include corresponding angles, alternate interior angles, alternate exterior angles, and consecutive interior angles, with specific relationships such as equality or supplementary.

Front

What is the definition of a transversal?

Back

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

Front

If angle E is 70 degrees, what is the measure of its supplementary angle F?

Back

110 degrees.
