Answer:
Step-by-step explanation:
We'll use the Pythagorean theorem. (a^2 + b^2 = c^2)
Triangle 1- 4^2 + 5^2 = 6^2 (16 + 25[tex]\neq[/tex]41)
Triangle 2- 15^2 + 20^2 = 25^2 (225 + 400=625) 625 = 25^2
Triangle 3- 15^2 + 36^2 = 39^2 (225 + 1296 = 1521) 1521 = 39^2
Triangle 4- 5^2 + 13^2 = 14^2 (25 + 169 [tex]\neq[/tex] 194) 14^2= 196
Therefore Triangles 2 and 3 are correct
