Geometry Final Exam Review

Front

What is a 90° clockwise rotation?

Back

A transformation that turns a figure 90 degrees in the clockwise direction around a fixed point.

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.

Front

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.

Front

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 convert radians to degrees?

Back

Front

What is the sum of (2x^2 + 5x - 7) and (3 - 4x^2 + 6x)?

Back

The sum is -2x^2 + 11x - 4.

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal. They are equal when the lines are parallel.

Front

What is a transformation in geometry?

Back

A change in the position, size, or shape of a figure. Types include translation, rotation, reflection, and dilation.

Front

What is the definition of vertical angles?

Back

Angles that are opposite each other when two lines intersect. They are always equal.

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.
