Geometry Vocabulary

3. The set of all points equidistant from a point in a plane.
5. Two lines are parallel if they lie in the same plane and do not intersect.
6. Two lines are perpendicular if they intersect to form right angles.
7. A transformation that slides each point of a figure the same distance in the same direction
10. The mapping, or movement, of all points of a figure in a plane according to a common operation, such as translation, reflection or rotation.
12. a given direction, such as 90 degrees clockwise.
13. The result of a transformation.
14. A figure before a transformation has taken place.
15. A dot is used to symbolize it

1. The point at which two or more lines intersect or cross.
2. A part of a line between two points on the line. indicates the line segment between points A and B.
4. A transformation of a figure that creates a mirror image, “flips,” over a line.
8. A transformation that turns a figure about a fixed point through a given angle
9. A figure created by two distinct rays that share a common endpoint (also known as a vertex). angle ABC or angle B or angle CBA indicates the same angle as vertex B.
11. One of the undefined terms of geometry that represents an infinite set of points with no thickness and its length continues in two opposite directions indefinitely
