Answer :
2 km, 16 km and 20 km are the sides of a right triangle .yes , it is a right triangle
Lets explain how to check the sides lengths which formed a right angled triangle
In triangle ABC :
If AC is the longest side in length
If (AC)² = (AB)² + (BC)²
Then, AB , BC , AC formed a right angle triangle in ∠B (opposite to AC) is a right angle and AC is the hypotenuse
The lengths of the sides of the triangle are 12 km, 16 km, 20 km
∵ The length of the longest sides is 20 km
- Find its square
∵ (20)² = 400
∴ The square of the length of the longest side is 400
∵ The length of the shortest sides are 12 km and 16 km
- Find the sum of their squares
∵ (12)² + (16)² = 144 + 256 = 400
∴ The sum of the squares of the lengths of the shortest sides is 400
∵ 400 = 400
∴ The sides of 12 km, 16 km and 20 km are the sides of
a right triangle
yes , it is a right triangle
