  1. 6.6 Special Quadrilaterals SUMMARIZING PROPERTIES OF QUADRILATERALS 1 GOAL EXAMPLE 1 By now you should now the distinguishing properties of each of the seven types of quadrilaterals we have studied. DO YOU???

  2. EXAMPLE 2 Extra Example 1 ABCD has at least two congruent consecutive sides. What quadrilaterals meet this condition? Hint: There are three. rhombus, square, kite

  3. F A B G E D C H Extra Example 2 When you join the midpoints of the sides of an isosceles trapezoid in order, what special quadrilateral is formed? Why?

  4. 6.6 Special Quadrilaterals PROOF WITH SPECIAL QUADRILATERALS 2 GOAL EXAMPLE 3 You should know the different methods used to show a quadrilateral is a specific shape. You will use either the definition of the shape or one of the theorems. This is explained in the concept summary found on page 365. Note: These are specific for rhombuses!

  5. Extra Example 3 The coordinates of ABCD are A(–2, 5), B(1, 8), C(4, 5), and D(1, 2). What are at least two ways to show that ABCD is a rhombus?

  6. EXAMPLE 4 Checkpoint The diagonals of RSTQ are perpendicular. What quadrilaterals meet this condition? square, rhombus, kite

  7. EXAMPLE 5 Extra Example 4

  8. The diagonals of ABCD intersect at point N to form four congruent isosceles triangles: What type of quadrilateral is ABCD? Extra Example 5

  9. Checkpoint The diagonals of ABCD are congruent. and What kind of figure is ABCD ? isosceles trapezoid

  10. QUESTION: At least two opposite angles of EFGH are congruent. What kind of quadrilateral might it be? ANSWER: parallelogram, rhombus, rectangle, square, kite
