#### Solution

1.5 cm, 2 cm, 2.5 cm

(1.5)2 = 2.25

(2)2 = 4

(2.5)2 = 6.25

Here,

2.25 + 4 = 6.25

(1.5)^{2} + (2)^{2} = (2.5)^{2}

The square of the length of one side is the sum of the squares of the lengths of the remaining two sides. Hence, these are the sides of a right-angled triangle.

Right angle will be in front of the side of 2.5 cm measure.
