Question

If the lengths of two sides of the triangle are 6.5 cm and 7.2 cm, then what will be the length of the third side?​

Answer 1

Answer:

It is known that the sum of the two sides of a triangle is greater than the third side, so,

thirdside<5+7

thirdside<12

And,

thirdside>7−5

thirdside>2

Therefore, 2<thirdside<12.

Hence, the third side of the triangle falls between (2,12).

Answer 2

Answer:

Step-by-step explanation:

• The sum of the lengths of any two sides in a triangle is always greater than the length of the third side in the triangle.
• The difference of the lengths of any two sides in a triangle is always lesser than the length of the third side in the triangle.

Side 1 = 6.5 cm

Side 2 = 7.2 cm

Side 3 = ?

Side 3< 7.2-6.5  

Side 3< 0.7

and

Side 3> 7.2+6.5

Side 3> 13.7

∴ the length of side will be between 0.7cm to 13.7cm
