PARKING Stephanie is drawing the layout of a parking lot on a coordinate grid and needs to verify that two sides meet in a right angle. In her sketch, one side of the parking lot has endpoints A(0,0) and B(50,0). The
second side of the parking lot has endpoints B(50,0) and C(18, 24). How can Stephanie prove that the two
sides of the parking lot meet in a right angle? Select all that apply.
® Find the slopes of AC and CB. If the product of the slopes is -1, then the sides meet in a right angle.
B Find the slopes of AB and AC. If the product of the slopes is -1, then the sides meet in a right angle.
© Find the slopes of CB and AB. If the slope of AB is the opposite of the slope of AC, then the sides meet in
a right angle.
Find AB, BC, and AC. If AB + BC = AC, then the sides meet in a right angle.
Find AB, BC, and AC. IfAB2+ BC = AC?, then the sides meet in a right angle.

A straight angle was formed when Tanisha arranged the three angles. This shows that the sum of the measures of the three angles in the triangle is equal to the straight angle, that is, the angle sum is 180 degrees. Also, this shows that whatever the position of the three sides of the triangle is, the total degrees of the angles is always 180.
