Geometry Final Review Part 1

Front

What is the midpoint formula for two endpoints (x1, y1) and (x2, y2)?

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

Front

Solve for c: 2c + 4 = 30

Back

c = 13

Front

Find the slope of the line given two points (x1, y1) and (x2, y2).

Back

Slope = (y2 - y1) / (x2 - x1)

Front

What are angles 1 and 7 if they are formed by a transversal intersecting two parallel lines?

Back

Alternate Interior Angles

Front

What are angles ∠SUV and ∠VUX if they are formed by two intersecting lines?

Back

Supplementary Angles

Front

What is the definition of vertical angles?

Back

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

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose sum is 180 degrees.

Front

What is the definition of alternate exterior angles?

Back

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

Front

What is the definition of corresponding angles?

Back

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

Front

What is the formula for the area of a triangle?

Back

Area = (base * height) / 2
