Geometry Review

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines in relation to a transversal. They are equal in measure.

Front

What is a linear pair of angles?

Back

Two adjacent angles that form a straight line. Their measures add up to 180 degrees.

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two parallel lines. They are equal in measure.

Front

What are vertical angles?

Back

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

Front

If m∠RST = (12x - 1)° and m∠RSU = (9x - 15)°, how do you find x?

Back

Set up the equation (12x - 1) + (9x - 15) + 53 = 180 and solve for x.

Front

What is the sum of the interior angles of a triangle?

Back

The sum is always 180 degrees.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What is the Pythagorean theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse.

Front

What are consecutive interior angles?

Back

Angles that are on the same side of the transversal and inside the two parallel lines. They are supplementary.

Front

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

Back

The measure of an exterior angle is equal to the sum of the measures of the two non-adjacent interior angles.
