Question

Can the angles ${110}^o,{80}^o,{90}^o$ & ${105}^o$ be the angles of quadrilateral?

• A. Yes
• B. No
• C. Cannot predict
• D. None of the above

Answer 1

Answer: (B)

No

We know, by angle sum property, the sum of angles of a quadrilateral is ${360}^o$.

Here, the sum of angle will be $={110}^o+{80}^o+{90}^o+{105}^o={385}^o>{360}^o$.

Hence, the given angles cannot be the angles of a quadrilateral.
$\therefore$ The answer is No.

That is, option $B$ is correct.
