Question
A quadrilateral has two of its angles as 30∘ and 40∘. What type of quadrilateral can it be?
Answer: Option A
:
A
In square and rectangle each angle is 900.
In a parallelogram, two adjacent angles have to be either equal or supplementary. The angles 30∘ and 40∘are neither supplementary nor equal. So, the twoangles cannot belong to a parallelogram.
Fortrapezium, there are no such restrictions. So, the given qudrilateral is a trapezium.
