1
Geometry Point Line Line segment Ray Plane Parallel lines Intersecting lines Angles

2
Geometry Point An exact location in space Line An endless collection of points along a straight path Line segment Part of a line that has two endpoints.A.A

3
Geometry Ray Part of a line that has one endpoint and extends endlessly in the other direction Plane An endless, flat surface that is named by any three points not on the same line..A.B.C

4
Geometry Parallel Lines Lines do not intersect but are in the same plane Intersecting Lines Lines meet at one point Perpendicular Lines Lines form a right angle

5
Angles An angle is formed when two rays have the same endpoint. This endpoint is called the vertex. The two rays that form the angle are called sides.

6
Angles There are four types of angles Right angle Straight angle Acute angle Obtuse angle

7
Right Angles Forms a square corner Forms a 90 degree angle. Use a corner of your index card to make sure you a have a right angle 90 degrees

8
Straight Angle Forms a straight line Angle is 180 degrees Use the edge of your index card to make sure you have a straight angle. 180 degrees

9
Acute Angles Forms an angle that is less than a right angle Angle is less than 90 degrees

10
Obtuse Angles Form an angle that is more than a right angle Angle is more than 90 degrees
