Question 978728: The sum of two opposite anglesvof a parallelogram is 130 find all the angles of the parallelogram Answer by Theo(13342) (Show Source):
You can put this solution on YOUR website! the opposite angles of a parallelogram are equal.
the adjacent angles of a parallelogram are supplementary.
the opposite angles must be 130/2 = 65.
the adjacent angles must be 180 - 65 = 115.
sum of each pair of opposite angles is 130 and 230.
sum of those is 360 as it should be since the sum of the internal angles of any quaderilateral is 360.
