Respuesta :
Opposite sides being parallel proves that hte figure is a parallelogram. The sides only appear to be equal so his conclusion is not valid. He would need to show that 2 adjacent sides of the parallelogram are equal ( using the distance formula) to prove that it is a rhombus.
Answer:
No, it is not.
Step-by-step explanation:
Proving the opposite sides are parallel is the correct first step. If the quadrilateral is not a parallelogram, it cannot be a rhombus.
After knowing the quadrilateral is a parallelogram, we must know whether the sides are congruent. To do this, we must use the distance formula to find the length of each side.
