Question

Two sides of a triangle are 3 cm and 8cm. If the triangle is isosceles, then the possible value of third
side is​

Answer 1

Answer:

8

Step-by-step explanation:

Because two sides are equal in isoscles tringle and max value .So third side would either be equal to 3 or 8 since 8 is highest value so possible value of third side would be 8

Answer 2

Answer -

• Possible value of third side is 8cm.

⠀

Explanation -

• Since, the given triangle is an isosceles triangle.

⠀

➛Therefore, it's two sides will be equal in length.

Now, it is given that two sides of the triangle is 3cm and 8cm.

⠀

According to the question

➛ Third side will be equal to one of the given sides because the given triangle is an isosceles.

⠀

✧ For any triangle with sides let say a,b,c, then

⠀⠀⠀★ a + b > c

⠀⠀⠀★ c + b > a

⠀⠀⠀★ c + a > b

Case I

• Let the third side be 3cm

➛ 3 + 3 = 6 < 8

⠀

So, the third side of 3 cm will not possible.

⠀

Case II

• Let third side be 8 cm

➛ 8 + 3 > 8

➛ 8 + 8 > 3

⠀

So, 8 cm is the third side.

⠀

Hence,

• Possible value of the third side will be 3cm or 8cm.
