**2)**__Would there be a consequence if the lines were not perpendicular?__

**If there are non-perpendicular lines, then the lines will form obtuse*

angles (greater than 90 degree angles) or acute angles (less than 90

degreeangles (greater than 90 degree angles) or acute angles (less than 90

degree

*angles). and in my picture, the baseball field would not be a*

diamond, it would just be different angles.

__How do you determine the slope of perpendicular lines?__

***You can determine the slope of perpendicular lines If you visualize**

a line with positive slope (so it's an increasing line), then the

perpendicular line must have negative slope (because it will be

a decreasing line). So perpendicular slopes have opposite signs.a line with positive slope (so it's an increasing line), then the
