The angle created by ray ox and ray oz is angle . the two rays that create yox are ray ox and ray . the center of the circle is point .

The answers

1. XOZ

2. OY

3. O

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1
