## Opposite Angles of Parallelogram

 Area of Parallelogram Opposite Angles of Parallelogram Adjacent Angles of Parallelogram Diagonal Of Parallelogram Difference & Similarity between Rectangle & Parallelogram Difference & Similarity between Square & Parallelogram Difference & Similarity between Square, Rectangle & Parallelogram Properties of Parallelogram

 Measure of opposite angles of parallelogram is always equal. Example 1: Observe the following diagram of parallelogram ABCD: Solution: In the above parallelogram ABCD: Angle A = Angle B Angle C = Angle D Because opposite angles of parallelogram are equal. Example 2: In the given parallelogram PQRS, Angle P = 50 degree and angle Q = 130 degree. Find the measure of remaining angles. Solution: In the given parallelogram PQRS: Angle P = 50 degree (given) Angle Q = 130 degree (given) As we know that opposite angles of parallelogram are equal, so we get: Angle P = Angle R = 50 degree Angle Q = Angle S = 130 degree And we get the following resultant diagram:
