  1. B A A (-2, -1) B (2, 5) find the slope of AB find the slope of a line perpendicular to AB Find the midpt of AB find AB (the length of the segment . . .hint: distance from A to B)

  2. Most specific name for QUAD? Q (0, 6) U (6, 2) A (-1, -2) D (-7, 2) // sides trap kite or quad Q isos D U rect rhom A I show 1 right angle (use slopes!) I show diagonals ┴ (slopes again)

  3. Most specific name for QUAD? Q (0, 6) U (6, 2) A (-1, -2) D (-7, 2) Step 1: find the slope of all 4 sides parallelogram Both pairs of opp sides are //, so it is a parallelogram. Step 2: Check the slopes of a pair of consecutive sides to see if they are perpendicular. Q m = -2/3 m = 4/7 -2/3 and 4/7 are not opp reciprocals, so this is NOT a rectangle. D U Step 3: Check the slopes of the diagonals to see if they are perpendicular. m = -2/3 m = 4/7 A m = 0 m = 8/1 The slopes are not opprecips, so this is NOT a rhombus
