Don't be a smart aleck @DrBob222.

A triangle has 3 sides, so there will be 3 sides to connect the bases together. Count up the vertices and faces and make sure there is the correct amount.
good suggestion, @Trying, but
(a) "connected by three rectangles" allows for many interpretations
(b) no question was even asked.
