How many triangles can be drawn having its angles as 530, 640 and 630? Give reason for your answer.
Answer: infinitely many
Solution.
Infinitely many triangles can be drawn having its angles as 530, 640 and 630
The sum of given angles = 530 + 640+ 630 = 1800
Here, we can see that sum of all interior angles of triangles is 1800, so infinitely many triangles can be drawn depending on the lengths of its sides.
So, infinitely many triangles can be drawn from the given angles.
