Question

Two adjacent angles of a parallelogram are 70° and 110° respectively. Find the other two angles of it.

Sum

Solution

Given two adjacent angles of a parallelogram are 70° and 110° respectively.

Since, we know that opposite angles of a parallelogram are equal

∴∠C = ∠A = 70° and ∠D = ∠B = 110°
