7.5 Using a Midsegment in the Coordinate Plane
Points Y and Z are movable in the Applet below.
Find the length of the midsegment[math][/math]in trapezoid [i]STUV[/i].
[b]Step 1 [/b]Find the lengths of [math]\overline{SV}[/math]and [math]\overline{TU}[/math] by using the distance formula.
[b]Step 2 [/b]Multiply the sum of [math]\overline{SV}[/math] and[math]\overline{TU}[/math] by [math]\frac{1}{2}[/math].
[b]Step 3 [/b]Double-check your answer by graphing [i]YZ[/i] in the Applet. Do you think you got the correct answer for Step 2? Why or why not?
