GEO Ch 3.1 Angles & Transversals

Front

What are skew lines?

Back

Skew lines are lines that do not intersect and are not parallel. They exist in different planes.

Front

What is the sum of the angles in a triangle?

Back

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

Front

What are complementary angles?

Back

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

Front

What are supplementary angles?

Back

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

Front

What is a transversal?

Back

A transversal is 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 alternate interior angles?

Back

The alternate interior angles are equal.

Front

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

Back

The corresponding angles are equal.

Front

What is the measure of angle 8 if it is an exterior angle and the two interior angles are 55 degrees and 45 degrees?

Back

The measure of angle 8 is 100 degrees.

Front

Solve for y: 2y + 10 = 80

Back

y = 35.

Front

Solve for x: 3x + 12 = 48

Back

x = 12.
