10-9-2013 Patty Paper Geometry!

Yesterday we found out that a perpendicular line is the shortest distance from a point to a line.

Do you remember the name of the angle that a perpenticular line makes?  What symbol do we use to show this angle?

Tell your neighbor!

Can you find other examples of perpendicular lines in the classroom?  Be ready to share!

Bonus question, how many perpendicular lines are in a square?

How can we name those angles?
