Question

e A scalene triangle has a longest side. A scalene triangle has a largest angle. The largest angle in a scalene triangle is opposite the longest side lementioned that there oposite the long

identify as valid or invalid

Answer 1

In a scalene triangle, all the sides are of different lengths and all the (interior) angles are of different measures.

In such a triangle, the shortest side is always opposite to the smallest angle and similarly the longest side is always opposite to the largest angle.

Therefore, very clearly from the given statements :

A scalene triangle has a longest side.

A scalene triangle has a largest angle.

It can can be concluded as :

The largest angle in a scalene triangle is opposite the longest side.

Thus it is valid.
