Geometry - Using Definitions to Solve

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 definition of perpendicular lines?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

Front

If two lines are parallel, what can be said about their slopes?

Back

If two lines are parallel, their slopes are equal.

Front

What is the relationship between complementary angles?

Back

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

Front

What is the relationship between supplementary angles?

Back

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

Front

If ∠LUV is 21 degrees and ∠LUP = x + 4, what is the value of x if ∠PUV = 2x - 1?

Back

x = 6, ∠PUV = 11 degrees.

Front

What is the formula for finding the measure of an angle in a triangle?

Back

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

Front

What is the definition of a transversal?

Back

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

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two lines and on opposite sides of a transversal.

Front

What is the definition of a line segment?

Back

A line segment is a part of a line that is bounded by two distinct endpoints.
