Question

③ How many traingles can be
drawn having its angles
45, 65 and 72 ? Give reason​

Answer 1

Answer: None

Explanation: None, the sum of given angles = 45° + 64° + 72° = 181° ≠ 180°.

Hence, we see that sum of all three angles is not equal to 180°. So, no triangle can be drawn with the given angles.

Answer 2

Answer:

Infinitely many triangles,

The sum of given angles = 45 + 65 + 72 = 180

Here, we see that sum of all interior angles of triangle is 180°, so infinitely many triangles can be drawn.
