WebThe diagonals of a rhombus are equal. Sometimes There is one right angle in a parallelogram and it is not a rectangle. Never An equiangular rhombus is a square. Always The opposite angles of a parallelogram are supplementary. Sometimes The diagonals of a rectangle are the bisectors of the angles. Sometimes A square is a rectangle. Always WebA kite is a quadrilateral, a closed flat geometric shape in which two sets of neighboring or adjacent sides are congruent (equal in length). Its diagonals meet at right angles. ... Angles opposite to the main diagonal are equal. $\angle C = \angle B = 109^\circ$ Four friends are flying identical-sized kites at a park. Each kite has diagonals of ...
