Question

A parallelogram whose vertices have coordinates R(1, -1), S(6, 1), T(8, 5), and U(3, 3) has a shorter diagonal of ___ .
shorter diagonal =

Answer 1

if you draw it you see the shorter diagonal is from U to S so find that distance\[d=\sqrt(6-3)^2+(1-3)^2\]
sqrt should be over whole right side
