Answer:
-------------------
Find the length of the third side:
- AC = P - (AB + BC)
- AC = 25 - (8.5 + 6.3)
- AC = 10.2
AC is the longest side compared to other sides.
Use Pythagorean theorem to verify if AC is the hypotenuse:
- AC² = AB² + BC²
- 10.2² = 8.5² + 6.3²
- 104.04 = 72.25 + 39.69
- 104.04 = 111.94
This is false equality, hence ΔABC is not right-angled.
