3 Αυγ 2023 · There are 5 basic ways to prove a quadrilateral is a parallelogram. They are as follows: Proving opposite sides are congruent. Proving opposite sides are parallel. Proving the quadrilateral’s diagonals bisect each other. Proving opposite angles are congruent.
In the given figure $PSDA$ is a parallelogram. Points $Q$ and $R$ are such that $PQ=QR=RS$ and $PA\parallel QB \parallel RC$. Prove that $\mathrm{ar}(PQE)=\mathrm{ar}(CFD)$.

21 Ιαν 2020 · We will use the properties of parallelograms to determine if we have enough information to prove a given quadrilateral is a parallelogram. Find missing values of a given parallelogram. Write several two-column proofs (step-by-step).
there can be many ways for doing so you can prove the triangles formed by the diagonals congruent and then find its value or you can use herons formula to do so.
Is the quadrilateral a parallelogram? Justify your answer. Repeat parts (a) and (b) for several other quadrilaterals. Then write a conjecture based on your results. Write the converse of your conjecture. Is the converse true? Explain. Proving That a Quadrilateral Is a Parallelogram. Work with a partner. Use dynamic geometry software. C B. 53. °.
If one pair of opposite sides is equal and parallel in a quadrilateral then it is a parallelogram. Theorem 1: In a Parallelogram the Opposite Sides are Equal. Proof: Given: ABCD is a parallelogram. To Prove: The opposite sides are equal, AB = CD and BC = AD. In parallelogram ABCD, compare triangles ABC and CDA. In these triangles: AC = CA ...
