Transversal Angles and Triangles Review

Front

What are Alternate Exterior Angles?

Back

Alternate Exterior Angles are pairs of angles that lie outside the two parallel lines and on opposite sides of the transversal. They are equal in measure.

Front

Identify the relationship between corresponding angles when two parallel lines are cut by a transversal.

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

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

Define Transversal in geometry.

Back

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

Front

What are Consecutive Interior Angles?

Back

Consecutive Interior Angles are pairs of angles that lie between the two parallel lines and on the same side of the transversal. They are supplementary, meaning they add up to 180 degrees.

Front

If two parallel lines are cut by a transversal, what can be said about the Alternate Interior Angles?

Back

Alternate Interior Angles are equal when two parallel lines are cut by a transversal.

Front

What is the measure of an angle if it is supplementary to a 70-degree angle?

Back

The measure of the angle is 110 degrees, since supplementary angles add up to 180 degrees.

Front

If angle x is 70 degrees, what is the measure of its vertical angle?

Back

The measure of the vertical angle is also 70 degrees, as vertical angles are equal.

Front

What is the measure of angle b if it is complementary to a 54-degree angle?

Back

The measure of angle b is 36 degrees, since complementary angles add up to 90 degrees.

Front

Find the measure of the missing angle if two angles are 50 degrees and 90 degrees.

Back

The measure of the missing angle is 40 degrees, since the sum of angles in a triangle is 180 degrees.
