Question

Can you construct triangle ABC with AB = 5 cm, ∠A = 80⁰ , ∠B = 120⁰?

• A. May be
• B. No
• C. Poor Data
• D. Yes

Answer 1

The correct option is B No

It is not possible to construct a triangle with the given dimensions because sum of it's two angles is more than ${180}^{\circ }$ $({80}^{\circ }+{120}^{\circ })$ = ${200}^{\circ }$.

For any triangle to exist, the sum of the three angles must be equal to ${180}^{\circ }$.
