Question

In which of the following cases the construction of a triangle is not possible? (A)Measures of 3 sides are given. (B)Measures of 2 sides and an included angle are given. (C)Measures of 2 angles and a side are given.(D) Measures of 3 angles are given.

Answer 1

(D)

Explanation:

This is because if you have 3 angles, there is an infinite amount of possible triangles. For example, if you have a triangle with the angles 30 degrees, 60 degrees, and 90 degrees, you could have any triangle with side ratios of 1:
`√(3)`:2.
