How to Graph Transformation on the Coordinate Plane: Rotation?
For rotating a shape \(90\) degrees counterclockwise:\((x, y)→(-y, x)\) For rotating a shape \(180\) degrees: \((x, y)→(-x, -y)\) For rotating a shape \(270\) degrees counterclockwise: \((x, y)→(y, -x)\) You should be able to assume the center of rotation to be the origin when working on the coordinate plane unless otherwise stated. You should be able […]
How to Graph Translations on the Coordinate Plane?
Translations on the Coordinate Plane – Example 1: Translations on the Coordinate Plane – Example 2: Translation: \(4\) units left and \(3\) units up. Solution: First, write the original coordinates of the points: \(I=(3, 0)\) \(G=(2, -4)\) \(H=(5, -2)\) Use this coordinate notation for translating each point: \((x, y)→(x+a, y+b)\) \(4\) units left →\(a=-4\) \(3\) […]
