Question

a triangle has sides with lengths of 6 millimeters, 8 millimeters, and 9 millimeters. is it a right triangle? yes no

Explanation:

Step1: Recall Pythagorean theorem

For a right triangle, \(a^2 + b^2 = c^2\), where \(c\) is the longest side. Here, \(c = 9\), \(a = 6\), \(b = 8\).

Step2: Calculate \(a^2 + b^2\)

\(6^2 + 8^2 = 36 + 64 = 100\)

Step3: Calculate \(c^2\)

\(9^2 = 81\)

Step4: Compare results

Since \(100
eq 81\), \(a^2 + b^2
eq c^2\).

Answer:

no
