What would you prove about a rhombus using pyth. thm?

• Prove diagonals are perpendicular

• Prove there are 4 congruent sides

• Prove opposite sides are parallel

• Prove there are 4 right angles

Prove the shape is a trapezoid.

• The slope of the parallel bases is 4/3

• The slope of the parallel bases is -4/3

• It is not a trapezoid because the slopes do not match.

• It is not a trapezoid because the legs are not parallel.
