EOC Review: Lines and Angles

Front

What are Alternate Interior Angles?

Back

Angles that are on opposite sides of a transversal and inside the two lines it intersects. They are congruent when the lines are parallel.

Front

What is the definition of Congruent Angles?

Back

Angles that have the same measure.

Front

What are Supplementary Angles?

Back

Two angles whose measures add up to 180 degrees.

Front

What is a Transversal?

Back

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

Front

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

Back

Corresponding angles are congruent.

Front

What are Vertical Angles?

Back

Angles that are opposite each other when two lines intersect. They are always congruent.

Front

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

Back

180 degrees.

Front

What are Complementary Angles?

Back

Two angles whose measures add up to 90 degrees.

Front

If ∠1 and ∠2 are supplementary and ∠1 measures 70 degrees, what is the measure of ∠2?

Back

∠2 measures 110 degrees.

Front

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

Back

Alternate exterior angles are congruent.
