Geometry Exam 6th

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie on opposite sides of a transversal and outside the two lines it intersects. They are equal when the lines are parallel.

Front

If two parallel lines are cut by a transversal, what is the relationship between corresponding angles?

Back

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

Front

How do you find the measure of an angle when given its supplementary angle?

Back

The measure of an angle plus its supplementary angle equals 180 degrees. If m∠A + m∠B = 180°, then m∠B = 180° - m∠A.

Front

What is the formula for finding the distance between two points (x1, y1) and (x2, y2)?

Back

The distance formula is d = √((x2 - x1)² + (y2 - y1)²).

Front

If m∠1 = 83° and m∠2 is an alternate interior angle, what is m∠2?

Back

m∠2 = 83° because alternate interior angles are equal when the lines are parallel.

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 vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

If two angles are complementary, what is the relationship between their measures?

Back

The measures of two complementary angles add up to 90 degrees.

Front

How do you determine if two lines are parallel using angles?

Back

If a transversal intersects two lines and the corresponding angles are equal, then the lines are parallel.
