Geometry Midterm Review

Front

What type of angle pair relationship do Angles 1 and 5 represent?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others.

Front

Define a ray in geometry.

Back

A ray is part of a line that has one endpoint and extends infinitely in one direction.

Front

How do you find the midpoint of two points (x1, y1) and (x2, y2)?

Back

The midpoint M is given by the formula M = (\frac{x1 + x2}{2}, \frac{y1 + y2}{2}).

Front

Identify the angles that have V as a vertex.

Back

The angles that have V as a vertex are B.

Front

What type of angle pair relationship do Angles 1 and 8 represent?

Back

Angles 1 and 8 are Alternate Exterior angles.

Front

What are vertical angles?

Back

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

Front

Define supplementary angles.

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What is the definition of corresponding angles?

Back

Corresponding angles are angles that are in the same position at each intersection where a straight line crosses two others.

Front

How do you calculate the distance between two points (x1, y1) and (x2, y2)?

Back

The distance D is calculated using the formula D = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}.

Front

What is the definition of alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of the transversal and inside the two lines.
