What is the midpoint of a line segment?
The midpoint is the point that divides the segment into two equal parts.

Define an angle.
An angle is formed by two rays with a common endpoint called the vertex.

What is a line segment?
A line segment is a part of a line that has two endpoints.

How is the distance between two points calculated?
The distance formula derives from the Pythagorean theorem.

Explain the concept of vertical angles.
Vertical angles are the angles opposite each other when two lines intersect; they are always equal.
