Question

Suppose a triangle has sides 3 4 and 5, which of the following must be true

Answer 1

You haven't given any options to select.
However, if this is the way of values we can check pythagoras theorem .

5^2 = 25

3^2 + 4^2
9 + 16
25

25 = 25

therefore we can say it is the right angle triangle
