A right triangle can have at most ? Of length 5. A) 3 sides B) 2 sides C) 1 side D) 0 sides?

The hypotenuse is the longest side opposite the 90° angle. If it was length 5 then you couldn't have another side of length 5 (or else the triangle would need another angle of 90° which is impossible).

So the only possibilities is if both legs were of length 5 (and the hypotenuse was 5√2). In that case you'd have a 45-45-90 right triangle.

Answer:
At most B) 2 sides.

b

b) 2 sides
