And one way to define concave quadrilaterals-- so let me draw it a little bit bigger, so this right over here is a concave quadrilateral-- is that it has an interior angle that is larger than 180 degrees. So for example, this interior angle right over here is larger than 180 degrees. And it's an interesting proof. Maybe I'll do a video. This video provides the student with a walkthrough on proving that a quadrilateral is a parallelogram.A quadrilateral is a square if and only if it is both a rhombus and a rectangle (i.e., four equal sides and four equal angles). Oblong: longer than wide, or wider than long (i.e., a rectangle that is not a square). [5] Kite: two pairs of adjacent sides are of equal length.Quadrilateral proofs A.

The interior angles of C B D are ψ , ψ , and ( 180 ∘ − θ) , and we know that the interior angles of any triangle sum to 180 ∘ . ψ + ψ + ( 180 ∘ − θ) = 180 ∘ 2 ψ + 180 ∘ − θ = 180 ∘ 2 ψ − θ = 0 2 ψ = θ. Cool. We've completed our proof for Case A.

The lemma is used in the first proof of the Theorem of Complete Quadrilateral. Proof #1. Parallelograms ARCQ and APGN have equal areas, and so have ARCQ and ASTU. Therefore, the same holds for the parallelograms PGHS and HTUN. This means that H lies on AV. Therefore, midpoints of segments CV, CH and CA lie on a line (parallel to AV).
