Question

 what are the properties of perpendicular lines

Answer 1

Hi Jen--

 

Best thing to do is draw them. (Do you know what they look like?)

 

So draw them if you can, look at them, and answer these questions:

 

1) do they intersect?

2) are the 4 angles they form all the same size?

3) is that size 90 degrees (like a letter L, even if that L is upside down or backwards)?

 

Those qualities together describe a pair of perpendicular lines.

 

Hope this helps, but post back if you're still stumped.
