Question

How many triangles can be constructed with side measurements 6 cm, 15 cm, 20 cm?

Answer 1

Answer:

Option: B is the correct answer.

         B.   Exactly one triangle.

Step-by-step explanation:

We are given the side lengths of a triangle as:

    6 cm, 15 cm and 20 cm.

We know that with the help of all the three side lengths of a given triangle a unique triangle is constructed.

( Whereas with the help of given three angle measures of a triangle infinite number of such triangles could be constructed with different side lengths)

            Hence, the answer is:

                      Option: B

Answer 2

Only one and only one triangle could be constructed with 3 defined sides length. Answer B
