Answer:
A, B, C
Step-by-step explanation:
Use a^2 + b^2 = c^2 in each case.
A.
3^2 + (sqrt(27))^2 = 6^2
9 + 27 = 36
36 = 36
A. does form a right triangle.
B.
8^2 + 15^2 = 17^2
64 + 225 = 289
289 = 289
B. does form a right triangle.
C.
5^2 + 5^2 = (sqrt(50))^2
25 + 25 = 50
50 = 50
C. does form a right triangle.
