Question

Which of the following polygon has NO opposite angles?

• A. Quadrilateral
• B. Triangle
• C. Polygon having more than $4$ sides.
• D. None of the above

Answer 1

The correct option is B Triangle

The only polygon which have no opposite angles is Triangle.

Here in the above figure triangle is shown and all the three angles are adjacent to any other angle. No two angles are opposite angles.

In Quadrilateral there are opposite angles as shown below.

In above figure, $\angle A$ and $\angle B$ are opposite angles.
And all other polygons having sides more than $3$ have opposite angles.
For example-

Hence, correct option is $\left(b\right)$.
