The midpoint of CD is M=(1, 2). One endpoint is C = (6, -2). Find the coordinates of the other endpoint, D.

Endpoint = (-4,6)

Step-by-step explanation:

To find any endpoint use the formula    

multiply each by 2  to simplify

    take the equations and simplify

6+ = 2                          -2+ = 4  =  

-6       -6                          +2       +2

    = -4                               =  6

To check use the Midpoint formula

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
