Question

While eating his favourite nacho chips, Rohit couldn’t help but relate the concepts of triangles he had learnt in Mathematics to the triangular chips! He measured the sides of different sized pieces and tabulated them as follows
: Nacho piece A : 8 mm, 14 mm, 7 mm
Nacho piece B : 6 cm, 6 cm, 6 cm
Nacho piece C : 4 cm, 5 cm, 9 cm
Nacho piece D : 1.1 cm, 3 cm, 1.8 cm

Which of the pieces out of above isn’t forming a triangle ?

Answer 1

Answer:

Nacho piece D doesn't form a triangle.

Step-by-step explanation:

RULE : sum of any two sides of triangle should be greater than the third side.

because, 1.1 cm + 1.8 cm = 2.9 cm < 3 cm
