HGeom - Chapter 3 Test

Front

What is the relationship between same-side interior angles when two parallel lines are cut by a transversal?

Back

Same-side interior angles are supplementary, meaning they add up to 180 degrees.

Front

What equation represents the sum of angles in a triangle?

Back

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

Front

How do you solve for an unknown variable in an equation involving angles?

Back

Isolate the variable by performing inverse operations on both sides of the equation.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside the two lines and on opposite sides of the transversal; they are equal when the lines are parallel.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined because it does not have a defined rise over run.

Front

What is the definition of supplementary angles?

Back

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

Front

What is the definition of complementary angles?

Back

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

Front

What is a transversal in geometry?

Back

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

Front

What is 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

How can you determine if two lines are parallel using angle relationships?

Back

If a pair of alternate interior angles are equal, then the two lines are parallel.
