Question

The measure of the angle formed by two intersecting perpendicular lines is 90°

true OR false

Answer 1

What do you think it is?

Answer 2

Take a guess if you really don't know and say why.

Answer 3

true ?

Answer 4

Umm good guess. You are right. The thing is that perpendicular lines have an inverse slope of the other.

for example

y=x
y=-x

slopes are inverse of each other and when you graph it they make perpendicular lines that create 90 degree angles.
