Question

Which of the following statements is true and would show that the 4 points are the vertices of a parallelogram? A. DA = AB = BC = CD = v17 B. AB = CD = v13; DA = BC = v17C. DB = v18; AC = v38

Answer 1

B. AB = CD = sqrt(13); DA = BC = sqrt(17)

This is because in a parallelogram, opposite sides are equal in length. In this statement, AB is equal to CD and DA is equal to BC, so opposite sides are equal. The values of AB, CD, DA, and BC are given as the square root of 13 and the square root of 17, which matches the condition of the statement.

In statement A, all sides are equal in length, which means the shape is a rhombus, not necessarily a parallelogram.
