CD: C(-2,2), D(0,-4)

anonymous · Answer

what is the formular?

anonymous · Answer

$$d=\sqrt{(x2-x1)^{2} + (y2-y1)^{2}}$$

anonymous · Answer

so to find AB you already know the coordinates so:
$$AB= \sqrt{(-3-0)^{2}+(8-2)^{2}}$$

anonymous · Answer

$$AB=\sqrt{(-3)^{2} +5^{2}}$$

anonymous · Answer

$$AB=\sqrt{9+25}$$

anonymous · Answer

$$AB=\sqrt{34}$$

anonymous · Answer

You could leave AB = square roof 34 or round it to 5.83

anonymous · Answer

Do the same to CD:
CD= spuare roof of [ (0- (-2) ^2) + (-4-2)^2 ]
CD= square roof of [ ( 0+2)^2 + (-6)^2 ]
CD= square roof of ( 4 +36) 
CD = square roof of 40 
CD = 2 square roof 10 or 6.32

anonymous · Answer

congruents or not based on it definition was : exacly the same. Since you know 2 of it leagth, can you said it was congruents or not? 
5.83 = 6.32 ( false ) => it NOT CONGRUENT! :)
