Answer:
All the measurements are correct
Step-by-step explanation:
What we have here are right triangles
For right triangles, the square of the hypotenuse (the side facing the right angle) equals the sum of the squares of the two other sides
Starting from the left;
a) 13^2 = 12^2 + 5^2
169 = 144 + 25
169 = 169
This triangle is valid
b) 25^2 = 24^2 + 7^2
625 = 576 + 49
625 = 625
This triangle is valid
c) 5^2 = 3^2 + 2^2
25 = 9 + 16
25 = 25
