On the contrary, a parallelogram is a slanting rectangle with two sets of parallel opposite sides. Start studying Properties of Parallelograms. Each diagonal of a parallelogram separates it into two congruent triangles. Here we have provided some parallelogram examples with solutions: Question 1: Find the measures of ∠C and ∠B in the parallelogram ABCD. Another property is that each diagonal forms two congruent triangles inside the parallelogram. The length of AB is equal to the length of DC. Solution: By the second property of parallelogram, opposite angles of a parallelogram are congruent. Sometimes the sides and angles may be equal while sometimes they may be different. Diagonals bisect each other. • If a parallelogram is known to have one right angle, then with the help of co-interior angles property, it can be proved that all its angles are right angles. Moreover, they are congruent which means the opposite sides are identical, and they coincide exactly when they are superimposed, or placed on top of each other. If the opposite angles of a quadrilateral are equal, it is a parallelogram. A: The six properties of a parallelogram are:(i) Opposite sides are parallel and congruent.

Now that you are clear on parallelogram definition, let’s see what are all the properties of parallelogram. Consider ABCD be a parallelogram and measure of angle C is 90°.Now, since ABCD is a parallelogram, then the measure of angle will be equal to measure of angle A, that is,m∠C = m∠A=90° (Opposite angles of a parallelogram are equal)and m∠A + m∠B = 180 (Corresponding angles)⇒ 90 + m∠B = 180⇒ m∠B = 90Also, m∠B = m∠D=90° (Opposite angles of a parallelogram are equal).Thus, m∠A = m∠B = m∠C = m∠D = 90°.Since all the angles of the parallelogram are equal to 90°, therefore ABCD is a rectangle, by the properties of a rectangle.Hence proved. Answer: The opposite sides are "parallel and congruent". Tags: Question 2. (ii) Each diagonal bisects the parallelogram into two congruent triangles.
