Solution
The correct option is A Acute angled triangle
An acute angled triangle has all three angles acute (less than 90°).
An obtuse angled triangle has one obtuse angle (greater than 90°) and two acute angles. Since the sum of all the interior angles of a triangle is equal to 180°, no triangle can have more than one obtuse angle.
A right-angled triangle has one of the three angles equal to 90°.
The angles of a triangle measured by Shreya are all less that 90°, so its an acute angled triangle.
