Question

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

Explanation:

Step1: Check side lengths

The side lengths \(LK = 3.31\), \(KM=4.88\), \(ML = 7.13\) are all different. So it is a scalene triangle.

Step2: Check angles

One of the angles (\(\angle K=120^{\circ}\)) is greater than \(90^{\circ}\). So it is an obtuse triangle.

Answer:

Scalene Obtuse
