1. To prove whether a given triangle is equilateral or not, what formula will you use? a. Midpoint Formula c. Slope Formula b. Distance Formula d. Perimeter Formula
Distance formula √(x2−x1)^2+(y2−y1)^2 which is an application of the Phythagorean theorem should be used to know the distance between points (x1, y1) and (x2, y2) which will prove if a given triangle is equilateral or not.
