Front

How do you find the slope between two points?

Back

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

Front

What is the value of x if angle A is 90° and angle B is 83°?

Back

Front

How do you find the measure of a missing angle in a triangle?

Back

The sum of angles in a triangle is 180°. Subtract the known angles from 180°.

A flat, two-dimensional surface that extends infinitely in all directions.

Front

What is the formula for the slope of a line?

Back

Slope (m) = (rise/run) = (y2 - y1) / (x2 - x1)

Front

What is the relationship between complementary angles?

Back

Two angles are complementary if their sum is 90°.

Front

What is the relationship between supplementary angles?

Back

Two angles are supplementary if their sum is 180°.

Front

How do you calculate the measure of an exterior angle of a triangle?

Back

The exterior angle is equal to the sum of the two opposite interior angles.
