Question

What is the length of line segment CD?* 6. #4 3 •C с 1 A B 4 6

Answer 1

you can use the formula to find the distance between two points

remember

Let

`\begin{gathered} P1(x_1.y_1) \\ P2(x_2,y_2) \end{gathered}`

the distance between P1 and P2 is

`d=\sqrt{(x_2-x_1_{})^2+(y_2-y_1)^2}`

Step 1

Let

P1=C(7,2)

P2=D(4,2)

Step 2

replace to find d

`\begin{gathered} d=√((x_2-x_1)^2+(y_2-y_1)^2) \\ d=√((2-2)^2+(4-7)^2) \\ d=√(-3^2) \\ d=√(9) \\ d=3 \end{gathered}`

so, the length of line segment CD is 3 units
