Answer: (1) sin A = cos B What is opposite of angle A is adjacent to angle B. Check all that apply. A rectangle with all sides equal and four right angles (2) Every rhombus is a square (3 Every trapezoid is a parallelogram 4 Every square is a rhombus 11. 1. rectangle 2. rhombus 3. square 4. trapezoid 1. Angles. These statements are true of any parallelogram, not only of rhombera . A rhombus is a type of parallelogram, and what distinguishes its shape is that all four of its sides are congruent.. Is a rhombus always a rectangle? It's a type of quadrilateral that is not a parallelogram. Which one of the following statements is always true? Answer: (2) 15 a) The diagonals of a rhombus are congruent. All 4 sides are congruent. Julie says that all quadrilaterals are rhombi. (British name: Trapezium) 1) sinA =cosB 2) sinA =tanB 3) sinB =tanA 4) sinB =cosB 5 A 12-foot ladder leans against a building and reaches a window 10 feet above ground. B. PQR is congruent to QPS. 37. d) The diagonals of a rhombus bisect the angles. Select all that apply. A rhombus is defined as a parallelogram with four equal sides. c) The diagonals of a rhombus bisect each other. You can use the following six methods to prove that a quadrilateral is a rhombus. No, because a rhombus does not have to have 4 right angles. Which one of the following statements is always true? Each of its four sides is parallel to one of other three. 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). Which of the statements below disproves her claim? PQRS is a rhombus. Check all that apply http://media.apexlearning.com/Images/201007/08/14b5641c-a799-4413-9dc9-62f93a1bb699.gif A. QPR is congruent to SPR. There are several formulas for the rhombus that have to do with its: Sides (click for more detail). The diagonals of parallelogram PQRS intersect at Z. Q. Which statements must be true? If quadrilateral PQRS is a kite, which statements must be true? A parallelogram with all sides equal 3. QP ≅ QR PM ≅ MR QR ≅ RS ∠PQR ≅ ∠PSR ∠QPS ≅ ∠QRS - 1809068 Diagonals PR and QS intersect at O. Characterize the following statements a TRUE or FALSE and give reason for your answer. If a pair of adjacent sides of a parallelogram is equal, it must be a rhombus or a square.
