[Geometry] Unit 3: Review

Front

What is the definition of corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others.

Front

What are supplementary angles?

Back

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

Front

How do you find the measure of an angle when given its supplementary angle?

Back

To find the measure of an angle when given its supplementary angle, subtract the measure of the known angle from 180 degrees.

Front

What is the relationship between alternate interior angles when two parallel lines are crossed by a transversal?

Back

Alternate interior angles are equal when two parallel lines are crossed by a transversal.

Front

What is the definition of parallel lines?

Back

Parallel lines are lines in a plane that never meet and are always the same distance apart.

Front

What is a transversal in geometry?

Back

A transversal is a line that crosses at least two other lines.

Front

What are vertical angles?

Back

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

Back

Adjacent angles are two angles that share a common side and a common vertex but do not overlap.

Front

How can you identify corresponding angles in a diagram?

Back

Corresponding angles can be identified by their position; they are in the same relative position at each intersection.
