If […] Prove that all four triangles so - 12882402 Which statement must be true? If RV = 12 and RT = 18, what is the length of SV? In right triangle RST, altitude TV is drawn to hypotenuse RS. 20. Trapezoids only have one pair of parallel sides. b) The diagonals of a rhombus are perpendicular. Diagonals bisect vertex angles. (1 A rectangle is a parallelogram ) A rhombus is a square (3) A quadrilateral is a trapezoid (4) A trapezoid is a parallelogram 12. Which statement must be true? What is the measure of the angle, to the nearest degree, that the ladder forms with the ground? A rhombus has two pairs of parallel sides. The last three methods in this list require that you first show (or be given) that the quadrilateral in question is a parallelogram: If all sides of a quadrilateral are congruent, then it’s a rhombus (reverse of the definition).
