Question 1070084: The measure of two exterior angles of a quadrilateral are 70 and 80. FIND the measure of the other two exterior angles if they are congruent? Answer by dhyanbir 2345(3) (Show Source):
You can put this solution on YOUR website! We know that sum of exterior angles of a quadilaterls are 360 degree.
70+80+x+x=360
2x=360-150=210
x=210/2
x=105 degree.
Both triangles are congurent.You look at your quadilateral properties.
