Question

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

Explanation:

Step1: Check for equal sides

In triangle \(KLM\), \(KM = LM=4.84\). So, it is an isosceles triangle (a triangle with at least two equal - sided is isosceles).

Step2: Check for angle types

All angles \(54^{\circ},54^{\circ},72^{\circ}\) are less than \(90^{\circ}\). A triangle with all angles less than \(90^{\circ}\) is an acute - angled triangle.

Answer:

Isosceles Acute
