QP ≅ QR PM ≅ MR QR ≅ RS ∠PQR ≅ ∠PSR ∠QPS ≅ ∠QRS - 1809068 Trapezoids only have one pair of parallel sides. Choice (4) is only true if A and B are both 45 degrees. A rhombus is defined as a parallelogram with four equal sides. Answer: (1) sin A = cos B What is opposite of angle A is adjacent to angle B. These statements are true of any parallelogram, not only of rhombera . Which statement must be true? (1 A rectangle is a parallelogram ) A rhombus is a square (3) A quadrilateral is a trapezoid (4) A trapezoid is a parallelogram 12. You can use the following six methods to prove that a quadrilateral is a rhombus. Julie says that all quadrilaterals are rhombi. If quadrilateral PQRS is a kite, which statements must be true? No, because a rhombus does not have to have 4 right angles. Which one of the following statements is always true? Which statements must be true? 1. rectangle 2. rhombus 3. square 4. trapezoid 1. It's a type of quadrilateral that is not a parallelogram. Which one of the following statements is always true? Prove that all four triangles so - 12882402 Check all that apply. 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). Q. PQRS is a rhombus. All 4 sides are congruent. Check all that apply http://media.apexlearning.com/Images/201007/08/14b5641c-a799-4413-9dc9-62f93a1bb699.gif A. QPR is congruent to SPR. The diagonals of parallelogram PQRS intersect at Z. A rhombus has two pairs of parallel sides. In right triangle RST, altitude TV is drawn to hypotenuse RS. Diagonals PR and QS intersect at O. If […] A parallelogram with all sides equal 3. Characterize the following statements a TRUE or FALSE and give reason for your answer. If RV = 12 and RT = 18, what is the length of SV?
