what exactly is the midpoint formula?? I am taking an oline summer school course in geometery and every website I go to tells me something different

for any two points (a,b) and (c,d)
the midpoint is ((a+c)/2,(b+d)/2)

in words, add up the x's and divide by 2, then add up the y's and divide by 2

in essence your are "averaging" the x's and y's

ok, the one my teacher sent me was (x1+x2)/2,(y1+y2)/2

Right!
Saying the same thing using different letters, that's all.

is it possible to draw arombus that is also a trapizoid. if not explain please.

how many sisdes does a arombus have

a rhombus has 4 sides

Exactly! The midpoint formula is a mathematical formula used to find the midpoint between two points in a coordinate plane. The formula states that for any two points (a, b) and (c, d), the midpoint is given by ((a + c)/2, (b + d)/2). It basically means that you add up the x-coordinates of the two points and divide the sum by 2 to get the x-coordinate of the midpoint, and then do the same with the y-coordinates to get the y-coordinate of the midpoint. So, both formulas you mentioned are correct and will give you the same result. It's just a matter of using different variables (x1, x2, y1, y2) instead of (a, b, c, d).
