Answer:
no
Step-by-step explanation:
Using the converse of Pythagoras' identity.
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = 81
81² = 6561
13² + 80² = 169 + 6400 = 6569
Since 6561 ≠ 6569 then they do not form a right triangle
Using reverse Pythagoras theorem, the three sides of lengths of triangle does not form right triangle.
What is reverse Pythagoras theorem?
Reverse Pythagoras theorem states that "the square of the longest side is equal to the sum of the squares on the other two sides then the triangle is right triangle".
What is right triangle?
A triangle in which "one angle is 90° and the other two sides are perpendicular to each other is called right triangle."
According to the question,
Three sides lengths of triangle 13, 80 and 81. In order to find this triangle is right triangle or not.
Let a = 13, b=80, and c = 81
Reverse Pythagoras theorem c² = a² + b²
(81)² = (13)² + (80)²
6561 = 169 + 6400
6561 ≠ 6569
Hence, using reverse Pythagoras theorem, the three sides of lengths of triangle does not form right triangle.
