  41. Example What theorem would we use to show that the quadrilateral is a parallelogram? Axis of symmetry Vertex

  42. Example What theorem would we use to show that the quadrilateral is a parallelogram? Axis of symmetry Vertex

  43. Example What theorem would we use to show that the quadrilateral is a parallelogram? Axis of symmetry Vertex

  44. Example What theorem would we use to show that the quadrilateral is a parallelogram? Axis of symmetry Vertex

  45. Example What value of x, makes the quadrilateral a parallelogram? Axis of symmetry Vertex

  46. Proving via Coordinates We can also prove that an object is a quadrilateral if we’re given the coordinates of the vertices by • Proving that both sets of sides are congruent • Proving that two sides are congruent and parallel • Proving that both sets of sides are parallel Proving congruency is easy via the distance formula, so let’s look at this one

  47. An example… Find all of the angles given the listed angle measure 130 1 4 2 7 5 8 6 Axis of symmetry Vertex

  48. Another example… We see these angles used in figures as well Find x & y 3y 6y 2x Axis of symmetry Vertex

  49. Or in a proof Write a proof 3 1 A B 4 2 7 5 C D 8 6 Axis of symmetry Vertex
