Question

10. Is the triangle whose
lengths of sides are 3 cm, 4
cm,5 cm is a right-angled
triangle?​

Answer 1

Answer:

yes it is an right angles triangle;

5 is the hypotenuse as it is the largest

so according to pythogoreas theorem

hypotenuse square = base square + perpendicular square

Therefore 5 square = 3 square + 4 square

25. = 9 + 16

25. = 25

therefore. hypotenuse = base and perpendicular

so it is an right angles triangle
