1

Point

* Tiny dot; location; has no space

2

Line

A collection of points that are side by side, going on forever

3

Plane

A set of points that align as a flat surface

4

Line segment

*-------* Part of a line with 2 end points

5

Ray

*----> A part of a line that includes one end point

6

Perpendicular lines

+ Two lines that intersect at right angles.

7

Parallel lines

= Two lines on the same plane that never intersect

8

What is the distance between two lines on a line?

The length of the shortest path between them

9

Angle

< The two rays with the same endpoint. Common endpoint is the vertex; the two rays are the sides of the angle

10

Circle

O The set of all points in a plane at a common distance, radius, from the center point

11

What is the distance around a circular arc (or arc length)?

A fraction of the circumference of the circle

12

Bisect

To cut into two pieces of equal size

13

Equilateral triangle

Δ A triangle with three equal sides
