Is a triangle with sides 6 cm, 8 cm and 11 cm right-angled?

Class 8Pythagoras TheoremGeometry

AYes, because $6 + 8 > 11$
BYes, it is like 6, 8, 10
CIt cannot be decided
DNo, because $6^{2} + 8^{2} \neq = 1 1^{2}$

Step-by-Step Solution

36 + 64 = 100

but

1 1^{2} = 121

. The squares do not match, so there is no right angle.

Answer: D) No, because

6^{2} + 8^{2} \neq = 1 1^{2}
