Front

How do you combine like terms in algebra?

Back

You add or subtract coefficients of the same variable. For example, in (2x^2 + 5x - 7) + (3 - 4x^2 + 6x), combine 2x^2 and -4x^2 to get -2x^2, and 5x and 6x to get 11x.

What are alternate exterior angles?

Back

Angles that are on opposite sides of a transversal and outside the two lines it intersects. They are equal when the lines are parallel.

What is a scale factor in geometry?

Back

A number that scales, or multiplies, some quantity. For example, a scale factor of 2 means the new figure is twice the size of the original.

Front

How do you identify a rotation transformation?

Back

Look for a figure that has been turned around a fixed point. The angle of rotation and direction (clockwise or counterclockwise) are key.
