To identify: the type of the quadrilateral
Answer to Problem 4ST2
Square
Explanation of Solution
Given:
Diagonals
Concept Used:
Theorem 5-7: the quadrilateral is a parallelogram if the diagonals of a quadrilateral bisect each other.
Theorem 5-12: The diagonals of a rectangle are congruent.
Theorem 5-13: The diagonals of a rhombus are perpendicular.
It is given that for the quadrilateral
Thus, by theorem 5-7, the quadrilateral
Also, it is given that
So, by theorem 5-12, it can be said that the parallelogram
Also, it is given that diagonals
Thus, by theorem 5-13, the parallelogram
Now, the parallelogram which is both a rhombus and a rectangle is actually a square.
