Geometry Final Review

Front

What is the formula to find the midpoint of a line segment with endpoints A(x1, y1) and B(x2, y2)?

Back

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

Front

If a line segment has endpoints A(8,2) and B(6,10), what are the coordinates of the midpoint?

Back

(7, 6)

Front

What is a parallelogram?

Back

A parallelogram is a quadrilateral with opposite sides parallel and equal in length.

Front

In a parallelogram, if one angle is x degrees, what are the measures of the other angles?

Back

The opposite angle is also x degrees, and the adjacent angles are (180 - x) degrees.

Front

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

Back

180 degrees.

Front

If two angles are complementary, what is the sum of their measures?

Back

90 degrees.

Front

What is the relationship between the angles formed by a transversal intersecting two parallel lines?

Back

Corresponding angles are equal, alternate interior angles are equal, and consecutive interior angles are supplementary.

Front

What is the formula for the area of a triangle?

Back

Area = (1/2) * base * height.

Front

What is the formula for the volume of a rectangular prism?

Back

Volume = length * width * height.

Front

If a line bisects an angle, what does that mean?

Back

It means that the line divides the angle into two equal angles.
