Question

can this formula can be used every time to find the fourth vertex or third vertex in a rectangle or triangle or rohombus or sclane trianlgle etc..

Answer 1

$Let M be the mid point of one diagonal formed by (2, -1) and (-2, 3) then using mid-point method;</p><p></p><p>Coordinate of M(22−2,2−1+3)=(0,1)</p><p>⇒(2x+3,2y+4)=(0,1)</p><p>⇒x=−3 and y=−2</p><p>∴(−3,−2) is coordinate of D$
