Use a straightedge and a compass to construct a segment of length AB+CD

I also just noticed that is saying construct a segment of the lenght of both of them so after you have both lenght measure them draw AB close point get CD and trace it over start from B and there you have the big segment which is made of both of them AB + CD

:)

Step-by-step explanation:

So basically get your compass and start by these steps

first get the total lenght of AB lets say its 100

when you go to make CD angle all you have to do

its trace same line and there you got both points same sizes

I hope that helped.
