We know that-longest side-xB2- -lt- other side-xB2- - other side-xB2- then is acute-The sides of the triangle are 6 cm- 12 cm and 13 cm-Since- 132-lt-62-122Thus- the triangle is an acute angled triangle-

Three sides of a triangle are 6 cm, 12 cm and 13 cm then
all three angles are acute
one angle is a right angle and others acute
one angle is obtuse, one acute and one right angle
one angle is obtuse and others acute

We know that,
longest side² < other side² + other side² then is acute.

The sides of the triangle are 6 cm, 12 cm and 13 cm.
Since, $13^{2} < 6^{2} + 12^{2}$
Thus, the triangle is an acute angled triangle.
