G.RLT.2 Checkpoint 2a, 2b, and Decathlon

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

Provide an example of a pair of supplementary angles using transversal t.

Back

Angles 3 and 13, or 6 and 7.

Front

What is the relationship between corresponding angles?

Back

They are angles that are in the same position on different parallel lines cut by a transversal.

Front

Define alternate interior angles.

Back

Angles that are on opposite sides of the transversal and inside the two lines.

Front

What are consecutive interior angles?

Back

Angles that are on the same side of the transversal and inside the two lines.

Front

What is the sum of the angles in a triangle?

Back

180 degrees.

Front

What is the relationship between alternate exterior angles?

Back

They are equal when the lines are parallel.

Front

How do you identify corresponding angles?

Back

Look for angles that are in the same relative position at each intersection.

Front

What is the definition of a transversal?

Back

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

Front

What is the measure of angle 6 if angle 14 is 70 degrees and they are corresponding angles?

Back

Angle 6 is also 70 degrees.
