Expressing Geometric Properties With Equations
Use Coordinates To Prove Simple Geometric Theorems Algebraically
State Standard:
Use coordinates to prove simple geometric theorems algebraically. For example, prove or disprove that a figure defined by four given points in the coordinate plane is a rectangle; prove or disprove that the point (1, √3) lies on the circle centered at the origin and containing the point (0, 2).
