Question
How many triangles can be drawn having its angles as $53^{\circ}, 64^{\circ}$ and $63^{\circ}$ ? Give reason for your answer.
✓

Answer

Infinitely many triangles,
The sum of given angles $=53^{\circ}+64^{\circ}+63^{\circ}=180^{\circ}$
Here, we see that sum of all interior angles of triangle is $180^{\circ}$, so infinitely many triangles can be drawn.
