1. What are the x- and y-intercepts of the function graphed at the right ? a. (0,2) and (0,3) b. (2,0) and (0,-3) c. (0,-2) and (3,0) d. (0,2) and (3,0) 5.1 warm-up 3 -3 -2 -1 0 1 2 3 x -3 1 2 3 y

2. 6.2 Properties of Parallelograms

3. Parallelograms Opposite sides are congruent Opposite angles are congruent Diagonals bisect each other Pardekooper

4. Lets try some problems x 0 127 0 Find x in a Parallelogram: Opposite angles are congruent x=127 Same side angles are supplementary y0y0 180-127 y=53 0

5. Lets try some problems x0x0 55 0 Find x: x0x0 55 0 Pardekooper Same side angles are supplementary X + 55 = 180 X = 180 - 55 X = 125

6. Lets try some problems 2x+4 7x-1 Find x: Remember opposite sides are congruent. 2x + 4 = 10 -4 -4 2x = 6 10 6x+2 2 2 x = 3 Pardekooper

7. Now find the sides 2x+4 7x-1 Find x: 6x + 2 6(3) + 2 10 6x+2 18 + 2 20 7x - 1 7(3) - 1 21 - 1 20 2x + 4 2(3) + 4 6 + 4 10 10 20 20 Pardekooper

8. Just one more item If three (or more) parallel lines cut off congruent segments on one transversal, then they will cut off congruent segments on every transversal.

9. Here comes the assignment.
