Suppose a triangle has sides 3, 4, and 5. which of the following must be true? a. the triangle in question is not a right triangle. b. the triangle in question is a right triangle. c. the triangle in question may or may not be a right triangle.

B.The triangle in question is a right triangle.

Step-by-step explanation:

The Converse of Pythagoras theorem says that if the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides then the triangle is a right triangle.

The given sides of triangle : 3, 4, and 5.

Here, Measurement of largest side = 5

Then ,

Also,

Hence, by the converse of Pythagoras theorem, the triangle in question is a right triangle.
