# How many unique triangles can be drawn with interior angles measuring 40°, 40°, and 100°?

###### Question:

## Answers

Answer:NoneExplanation:A unique triangle can be defined as a triangle that can be formed in one way.The various conditions that a triangle must satisfy so that it is unique :a) A triangle where the length of the three sides is known or given is a unique triangle.b) A triangle where two side lengths and their included angle is given is a unique triangle.c) A triangle where two angles and their included side is given is a unique triangle.d) A triangle where two angles and a non - included side length is known is a unique triangle.In the above question, we are given angles 40°, 40° and 100 degrees3 angles are known, no side length is given. The angles above can form a triangle called the obtuse triangle because their sum = 180° and one of the angles is great we than 90° However, this does not satisfy the criteria that makes a triangle unique. Therefore, no unique triangle(s) can be drawn with interior angles measuring 40°, 40°, and 100°.
