# Distance Formula

Finding distances on a coordinate plane and using coordinates to prove simple geometric theorems algebraically. Using coordinates to compute perimeters of polygons and areas of triangles and rectangles.

#### Mapped to CCSS Section# 6.G.A.3, HSG.GPE.B.4, HSG.GPE.B.7

Draw polygons in the coordinate plane given coordinates for the vertices; use coordinates to find the length of a side joining points with the same first coordinate or the same second coordinate. Apply these techniques in the context of solving real-world and mathematical problems. 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). Use coordinates to compute perimeters of polygons and areas of triangles and rectangles, e.g., using the distance formula.
