Given
sides of a triangles
Find
Determine whether each triangle is a right triangle.
Explanation

According to the pythagoras theorem , the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the two legs of the triangle.
a) 12 yd, 14 yd, 16 yd
so ,

hence it is not right triangle.
b) 15 km, 20 km, 25 km

hence it is a right triangle.
c) 45 mm, 60 mm, 75 mm

hence it is a right triangle.
Final Answer
Hence ,
a) it is not right triangle
b) it is a right triangle
