Question

answer
scalene obtuse scalene right
isosceles right isosceles acute
scalene acute equilateral
isosceles obtuse

Explanation:

Step1: Check side lengths

All side lengths \(6.53\), \(7.61\), \(6.08\) are different. So it's a scalene triangle.

Step2: Check angles

All angles \(50^{\circ}\), \(56^{\circ}\), \(74^{\circ}\) are less than \(90^{\circ}\). So it's an acute triangle.
