Question
The sides of some triangles are given below. Find out which ones are right-angled triangles ? : 1.5, 1.6, 1.7
✓
Answer
1.5² = 2.25, 1.6² = 2.56, 1.7² = 2.89 But, 2.25 + 2.56 ≠ 2.89 ∴ 1.5² + 1.6² ≠ 1.7² ∴ The above expression is not of the from (hypotenuse)² = (base)² + (height)² ∴ The sides of lengths 1.5, 1.6, 1.7 will not form a right-angled triangle.
