Front

What is the measure of ONE interior angle of a regular dodecagon?

Back

150 degrees.

Front

What are vertical angles?

Back

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

Front

What are adjacent angles?

Back

Adjacent angles are two angles that share a common side and a common vertex.

Front

What is a linear pair of angles?

Back

A linear pair of angles are two adjacent angles that form a straight line, summing up to 180 degrees.

Front

What are complementary angles?

Back

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

Front

What are supplementary angles?

Back

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

Front

If AD = 10, what is the value of BC if they are equal?

Back

BC = 10.

Front

How do you find the value of x in an equation?

Back

Isolate x on one side of the equation using algebraic operations.

Front

What is the slope of a line parallel to y = -1/3x - 8?

Back

The slope is -1/3.

Front

How do you write the equation of a line given a point and a slope?

Back

Use the point-slope form: y - y1 = m(x - x1).
