Question

which angle is the smallest?

Explanation:

Step1: Recall the triangle side - angle relationship

In a triangle, the smallest angle is opposite the shortest side.

Step2: Identify the shortest side

The lengths of the sides are \(4\mathrm{cm}\), \(8\mathrm{cm}\), and \(9\mathrm{cm}\). The shortest side is \(4\mathrm{cm}\).

Step3: Determine the angle opposite the shortest side

The side \(4\mathrm{cm}\) is opposite \(\angle H\).

Answer:

\(\angle H\)
