Geometry Semester 1

Front

What is an Exterior Angle?

Back

An exterior angle is formed by one side of a polygon and the extension of an adjacent side. It is equal to the sum of the two remote interior angles.

Front

How do you calculate the slope of a line given two points?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What are Alternate Exterior Angles?

Back

Alternate exterior angles are pairs of angles that lie outside the two lines and on opposite sides of the transversal. They are equal when the lines are parallel.

Front

If m∠YXV = 96°, what is m∠YXZ if they are supplementary?

Back

m∠YXZ = 180° - m∠YXV = 180° - 96° = 84°.

Front

List the side measures in order from shortest to longest: QM, QP, MP.

Back

MQ, MP, QP.

Front

What is the definition of a Corresponding Angle?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines in relation to a transversal. They are equal.

Front

What is the relationship between Interior Angles and Exterior Angles in a triangle?

Back

The sum of the interior angles of a triangle is always 180°. Each exterior angle is equal to the sum of the two opposite interior angles.

Front

How do you identify Remote Interior Angles?

Back

Remote interior angles are the two angles inside a triangle that are not adjacent to a given exterior angle.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What is the definition of a Transversal?

Back

A transversal is a line that intersects two or more lines at different points.
