The only triangle dimensions that give a right angle triangle are;
3) 15, 36, 39
4) 15, 20, 25
6) 16, 30, 34
<h3>How to identify a right angle triangle?</h3>
We are told that If a triangle has side lengths a, b, and c such that;
a² + b² = c² , then that triangle is a right triangle.
1) Using Pythagoras theorem, we can say that;
15² + 18² ≠ 21²
Thus, this is not a right angle triangle.
2) Using Pythagoras theorem, we can say that;
16² + 20² ≠ 24²
Thus, this is not a right angle triangle.
3) Using Pythagoras theorem, we can say that;
15² + 36² = 39²
Thus, this is a right angle triangle.
4) Using Pythagoras theorem, we can say that;
15² + 20² = 25²
Thus, this is a right angle triangle.
5) Using Pythagoras theorem, we can say that;
16² + 32² ≠ 48²
Thus, this is not a right angle triangle.
6) Using Pythagoras theorem, we can say that;
16² + 30² = 34²
Thus, this a right angle triangle.
