Answer:
NO
Step-by-step explanation:
It is a right triangle if the thee sides satisfy the following pythagorean triple rule/theorem, c² = a² + b², where,
c is the longest side = 50
a = 15
b = 49
Let's check:
50² = 15² + 49²
2500 = 2626 (this is not true).
Therefore, the triangle is not a right triangle. The answer is NO.
