# Vertical Angles Discovery

## DIRECTIONS:

Please do the following:
1) Use the LINE tool to construct 2 lines that intersect.
2) Use the INTERSECT tool to plot the point at which these 2 lines intersect.
3) Use the ANGLE tool to measure any 2 angles that are not adjacent each other.

**When you use this tool, you will click the THREE Points that form the Angle, as if you were naming it.**__Remember, VERTEX goes in the middle.__## 4)

What do you notice?

When you're done (or if you're unsure of something), feel free to check by watching the quick silent screencast below the applet.
