Question

20 the following side lengths form a triangle. 5, 2, 4 a true b false

Explanation:

Step1: Check triangle inequality

For three side lengths \(a\), \(b\), \(c\) (\(a\leq b\leq c\)), the triangle inequality states \(a + b>c\). Here \(a = 2\), \(b = 4\), \(c = 5\).

Step2: Calculate \(a + b\)

\(a + b=2 + 4=6\).

Step3: Compare \(a + b\) and \(c\)

Since \(6>5\), the triangle inequality holds.

Answer:

A. True
