MCQ
In $\triangle\text{ABC, AB = AC}$ and $\angle\text{B} = 50^\circ.$ Then $\angle\text{C}$ is equal to:
- ✓$50^\circ$
- B$130^\circ$
- C$40^\circ$
- D$80^\circ$
✓
Answer
Correct option: A.
$50^\circ$
Given: $\triangle\text{ABC, AB = AC}$ and $\angle\text{B} = 50^\circ.$
As, $AB = AC$
So, it is an isosceles triangle.
So $\angle\text{B} = \angle\text{C}$
$\angle\text{B} = 50^\circ$ (given)
$⇒\angle\text{C} = 50^\circ$
As, $AB = AC$
So, it is an isosceles triangle.
So $\angle\text{B} = \angle\text{C}$
$\angle\text{B} = 50^\circ$ (given)
$⇒\angle\text{C} = 50^\circ$
