Ever wondered how to calculate the slope of a triangle? Are you puzzled by the Pythagorean theorem or baffled by the concept of a base angle? Well, have no fear, geometry genius at your service! Calculating triangle slope might seem like you’re trying to understand an alien language, but trust us, it’s as easy as π (mathematical pie, that is!).
The Formula
Slope = (y2 - y1) / (x2 - x1)
This formula calculates the slope, or gradient, of a line in a triangle. The variables y2 and y1 represent the y-coordinates of two points on the line, and x2 and x1 represent the corresponding x-coordinates.
