### Trapezoid Format...:

I introduce the trapezoid concept which implies something is being trapped about the subject. http morning ... Every day I find something creative to do with my life. --Miles Davis Using trapezoid if it adds anything I find interesting. 1: no 2: no 3: h .... 4: yes, definitely 5: no 6: some 7: yes

Question:rectangle,rhombus, triangle, trapezoid

Answers:Only the rectangle has all of these properties. Some trapezoids also do, but those particular trapezoids are also rectangles. Those rhombi having all these properties are squares, which are special cases of rectangles. A triangle never has four angles, let alone right angles.

Question:rhombus,trapezoid rectangle or a parallelogram

Answers:Rectangle. A rhombus would only have congruent diagonals if it's a square. A trapezoid would only have congruent diagonals if it's isosceles. A parallelogram would only have congruent diagonals if it's a rectangle.

Question:I. rhombus II. parallelogram III. square IV. trapezoid A) I, II, III B) None of These C) I D) II

Answers:Every rectangle is a parallelogram and a trapezoid. But only SOME rectangles are rhombuses and/or squares. II and IV are correct.
