Web13 jun. 2024 · The diagonals of a rhombus bisect the angles. In a trapezoid, the diagonals don’t make a right-angled triangle. In a rhombus, the diagonals form 4 congruent right-angled triangles. The isosceles trapezoid has two diagonals that are equal. Rhombus doesn’t have equal diagonals unless it’s a square. Every rhombus has two diagonals connecting pairs of opposite vertices, and two pairs of parallel sides. Using congruent triangles, one can prove that the rhombus is symmetric across each of these diagonals. It follows that any rhombus has the following properties: Opposite angles of a rhombus have … Meer weergeven In plane Euclidean geometry, a rhombus (plural rhombi or rhombuses) is a quadrilateral whose four sides all have the same length.
