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.

[8.G.B.8] - Apply the Pythagorean Theorem to find the distance between two points in a coordinate system.
- Pythagorean Theorem
For any right triangle, the sum of the squares of the measures of the legs equals the square of the measure of the hypotenuse.

Derive the equation of a circle of given center and radius using the Pythagorean Theorem; complete the square to find the center and radius of a circle given by an equation.
[GEO.G-GPE.A.2] -
Derive the equation of a parabola given a focus and directrix.
[GEO.G-GPE.B.4] -
Use coordinates to prove simple geometric theorems algebraically, including the distance formula and its relationship to the Pythagorean Theorem. 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).
