Question

How many triangles can be drawn having its angles as $45°,64°$ and $72°$ ?

• A. $0$
• B. $2$
• C. Only one
• D. $3$

Answer 1

The correct option is A

$0$

Explanation for the correct option:

Construct the triangle using given angle

According to the angle sum property, the sum of angles should be equal to $180°$.

We have,
$45°+64°+72°=181°$
Since, the sum is $181°\ne 180°$
Thus, no triangle can be formed with the given angles.

Therefore option (A) is correct answer.
