Question

What is the length of line segment CD?

Answer 1

Answer:

Assume you need to find distance CD, between points C(-2, 2), D(4, -4)

Use distance formula:

• $CD = \sqrt{(4 + 2)^2+(-4-2)^2} = \sqrt{72} = 6\sqrt{2}$ ≈ 8.5 units

Answer 2

Answer:

C(x1,y1)=(-2, 2), D(4, -4)

D(x2,y2)=(4, -4)

we have

the length of line segment CD

=$\sqrt{(x2-x1)²+(y2-y1)²}\\ \sqrt{(4+2)²+(-4-2)²}=8.48 units$
