Question

For the given measures of three sides of a triangle or three angles of a triangle, which among the following do not represent a triangle? (a) 5 cm, 4 cm, 2 cm (b) 1 cm, 2 cm, 3 cm (c) 8 cm, 15 cm, 17 cm (d) 30°, 40°, 110° (e) 110°, 50°, 60° (1) 70°, 65°, 45°​

Answer 1

Answer:

e) 110 50 60

b)1cm 2cm 3 cm

Answer 2

: => 1cm, 2cm and 3cm

(because for a ∆ with sides let a, b and c then,

• a+b> c
• b+c >a
• a+c >b

But 1 +2 = 3

this means that a + b = c..which is not possible

: => 110°, 50° and 60°

on applying the angle sum property

angle a + angle b + angle c = 180°

but here,

110°, 50° and 60° >180°

which is not possible

Hope it helps you ✨
