Question

1. classify each triangle using its side lengths.

(a)

(b)

Explanation:

Part (a)

Step1: Identify side lengths

The side lengths are \(2\) m, \(3\) m, and \(3\) m.

Step2: Classify by side lengths

A triangle with two equal - length sides is called an isosceles triangle. Since two sides (\(3\) m and \(3\) m) are equal, this triangle is isosceles.

Part (b)

Step1: Identify side lengths

The side lengths are \(3\) m, \(5\) m, and \(7\) m.

Step2: Classify by side lengths

A triangle with all three sides of different lengths is called a scalene triangle. Since \(3
eq5
eq7\), this triangle is scalene.

Answer:

(a) Isosceles triangle
(b) Scalene triangle
