Front

What are complementary angles?

Back

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

Front

If m

Back

5x - 2 + 3x + 4 = 90.

Front

What is the measure of an angle if it is equal to its complement?

Back

The measure of the angle is 45 degrees.

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

If two lines are parallel, what can be said about the angles formed when a transversal crosses them?

Back

The corresponding angles are equal, and the alternate interior angles are equal.

Front

What is the formula for the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the relationship between the angles in a linear pair?

Back

Angles in a linear pair are supplementary, meaning they add up to 180 degrees.

Front

If the measure of <5 is 42 degrees, what is the measure of <4 if they are equal?

Back

The measure of <4 is also 42 degrees.

Front

What is the definition of a transversal in geometry?

Back

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