  1. 6-1 classifying quadilaterals

  2. Ex. 1 Classifying a Quadilateral • Based on appearance, how many ways to classify DEFG? • Quad, parallelogram, rectangle • How many ways to classify WXYZ? • Quad, parallelogram, rhombus

  3. Ex. 2 Classify by Coordinates • Use distance formula and slope formula • Distance to see if sides congruent • Slope to see if sides are parallel • If slope is not the same, then not parallel • If slope is negative reciprocals, then perpendicular • Determine most precise name for LMNP • L(1,2) M(3,3) N(5,2) P(3,1) • Plot and find pieces • Rhombus

  4. Your Practice • Determine most precise name for ABCD with vertices A(-3,3) B(2,4) C(3,-1) D(-2,-2) • Square

  5. Ex. 3 Using Properties • Find values of the variables • Plug into other set to find y

  6. Ex. 3 Cont. • Solve for the variables
