Properties of Parallelograms-Proving Quadrilaterals are Parallelograms Bundle

Four worksheets on parallelograms.
The two worksheets are on the properties, perimeter and area of parallelograms. The exercises require to find missing sides, angles or diagonals of given parallelograms using their properties (equal opposite sides, equal opposite angles, supplementary consecutive angles, bisecting diagonals), find the perimeter and area of given parallelograms or find the sides and heights of parallelograms whose area or perimeter or both are known.
The other two worksheets have exercises that require to determine whether a given quadrilateral is a parallelogram or not. They aim to help students understand the five properties that can be used to prove that a quadrilateral is a parallelogram.
Detailed solutions are included.
