Question

ABCD is a quadrilateral and the measure of AB, BC , AD and AC are known. Which of the following parameter required for the construction of a unique quadrilateral ABCD ?

• A. $BD$
• B. $\angle ADB$
• C. $\angle BAC$
• D. $\angle BCA$

Answer 1

The correct option is A $BD$


Here we know the measure of AB, BC , AD and AC and we know that , by getting the measure of 3 sides and 2 one diagonal we can construct a unique quadrilateral.

So by getting the measure of BD with the given information we can construct the quadrilateral ABCD.
