True or false: This is an angle.
True, it's a straight angle
True or false: All lines that cross are perpendicular
False: They are only perpendicular if they make a 90 degree angle in the corner
Are all rectangles the same as squares?
No
True or false: these are perpendicular
False, they are not creating a right angle
