This is a football field enzone and the surface of the field is a plane

5

Angle

Angle- A figure formed by two rays with a common endpoint

This is a door frame that forms a 90 degree angle

6

Perpendicular lines

Perpendicular lines- Intersecting lines that form 90 degree angles

The bars on this fence form 90 degree angles to one another

7

Parallel LinesParallel lines- Lines in the same plane that don’t intersect

These tube rails on a road bridge are parallel to each other

8

Triangle

Triangle- A three sided polygon

This is a TV tray and the legs form aTriangle.

9

Right Triangle

Right Triangle- A triangle with one 90 degree angle

This is a power pole and the Wire, brace, and pole make up a right triangle
