Q11. In which case of the
following lengths of sides of a
triangle, is it possible to draw a
triangle?
O 3 cm, 4 cm, 7 cm
O2 cm, 3 cm, 7 cm
O 3 cm, 4 cm, 5 cm
O 3 cm, 3 cm, 7 cm​

Answer 1

Answer:

(i) No. It is not possible to construct a triangle with lengths of its sides 5 cm,4 cm and 9 cm because the sum of two sides is not greater than the third side i.e. 5+4 is not greater than 9.

(ii) Yes. It is possible to construct a triangle with lengths of its sides 8 cm,7 cm and 4 cm because the sum of two sides of a triangle is greater than the third side.

(iii) Yes. It is possible to construct a triangle with lengths of its sides 10 cm,5 cm and 6 cm because the sum of two sides of a triangle is greater than the third side.

(iv) Yes. It is possible to construct a triangle with lengths of its sides 2.5 cm,5 cm and 7 cm because the sum of two sides of a triangle is greater than the third side.

(v) No. It is not possible to construct a triangle with lengths of its sides 3 cm,4 cm and 8 cm because the sum of two sides is not greater than the third side

Answer 2

Answer:

• 3cm, 4cm, 5cm

THERE IS A FORMULA THAT SUM OF TWO SIDE MUST ME GREATER THEN THE THIRD SIDE.

3+4 not greater then 7

2+3 not greater then 7

3+4 greater than 7

3+3 not greater then 7
