True or false? if a parallelogram is inscribed in a circle, it must be a rectangle.

False.a square can be inscribed in a circle. the problem is that a square is a rectangle. i would stick with false, but don't be surprised to get it wrong given that a square is a rectangle.

The correct answer is:   [b]:   "false" .note:   all squares are rhombuses.              all rhombuses are parallelograms;             all squares are rectangles.            all rectangles are parallelograms.            so, all squares are parallograms.also, there are parallelograms that are not square, rectangles, or rhombues.these types of parallelograms can be inscribed in a circle.→ this fact alone makes the answer to this question:   "false" .note:   rectangles (that are not squares);             rhombuses (that are not rectangles or squares) ;           →   can be transcribed in a circle.      →   these examples further confirm that the answer to this question is:                             →   [b]:   " false " .

9/12 is the answer because 3/4 times 3 each is 9/12
