Answer 1

1)

A quadrilateral is just a four sided figure. That's all.

A trapezoid is a quadrilateral with two opposite sides parallel, and two opposite sides not paralle.

A parallelogram is a quadrilateral with both pairs of opposite sides parallel.

The reaming three are special parallelograms: 

      a rectangle is a parallelogram with a right angle (thus all four are right angles)

      a square is a rectangle with four equal sides

      a rhombus is a parallelogram with four equal sides (no right angles)

 

2) 

Use the definitions above to answer this one.
