Answer:
The slope formula can be used to prove that a triangle has
A. Congruent Sides
B. A right angle
C. Parallel sides
D.Congruent angles
Explanation:
The formula for finding the slope of a line on a coordinate plane is (y2 - y1) / (x2 - x1), where (x2, y2) and (x1, y1) represent two distinct points on the line. This is also known as "change in y over change in x" or "rise over run."
