Interactive classroom tools built at Riverside.

Perpendicular Gradients interactive. Two lines crossing at a right angle on a grid, with gradients that multiply to −1.

Perpendicular Gradients

Sec 3 · A Math Ch 7 · Coordinate Geometry

Drag two lines to a right angle, then watch a quarter turn show why their gradients multiply to make −1.
