Given: WXYZ is a parallelogram. View geomery notes 3.docx from MATH 150 at Howard University. In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. Theorem 8.10 DX} >D} Z 3. MEDIUM WXYZ is a parallelogram. Designed with Geometer's Sketchpad in mind . Find each measure. Video Transcript. W V. Give the gift of Numerade. WXYZ is a 1. Find each measure. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. DW} > DY} and 2. It is not a parallelogram because the angles of … Then ask the students to measure the angles, sides etc.. of inscribed shape and use the measurements to classify the shape (parallelogram). Consider the diagram and proof below. 2. 5 cm. WX} > YZ Can the following quadrilateral be proven to be a parallelogram based on the given information? No. x z. The vertices of quadrilateral PQRS are given below. Given parallelogram, WX} i YZ}, and WZ} i XY}. D I T T R DT ITR and DT = IR b. Pay for 5 months, gift an ENTIRE YEAR to someone special! WXYZ is a parallelogram 1. Use the diagram as a guide. 2D 2 ZR and 2T LI c. DT 1 TR and D7 | TR d DI 8TR and DT = TR 3. If the distance between the parallel sides of length 1 5 cm is 6 cm, then the distance between 1 2 cm parallel sides is 7 . A parallelogram has sides of 15 cm and 12 cm. statement reason 1. and bisect each other. ∠ ywx ≅ ∠wyz corresponding angles of congruent triangles are congruent. Q. Given 2. 522 Chapter 8 Quadrilaterals 8.3Show that a Quadrilateral is a Parallelogram Key Vocabulary •parallelogram, p. 515 Given a parallelogram, you can use Theorem 8.3 and Theorem 8.4 to prove statements about the angles and sides of the parallelogram. State the reason that enables you to deduce, from the information given that the quadralateral DIRT is a parallelogram. WXYZ is a parallelogram. Given: in quadrilateral wxyz , and bisect each other at point a. prove: quadrilateral wxyz is a parallelogram. given 2. wa = ya xa = za definition of bisection 3. m∠yaz = m∠xaw vertical angles theorem 4. sas criterion for congruence 5. Prove: m∠W = m∠Y, m∠X = m∠Z SOLUTION Statements Reasons 1. On question 4, angles 1 and 4 would not be congruent; they would be complementary, adding to 90º; the others look ok. On #5, the diagonals bisect each other so SX would equal the other half of the diagonal that SX is part of. Statements Reasons 1. All right, so in this question 23 they want us to find the value of X Z. Use the distance and/or slope formulas to determine if PQRS is a parallelogram.
