Now try to construct a triangle using a different set of measurements. This time, you’ll enter three angle measurements. Return
to the Calculator tab, and click the Clear button to begin a new calculation. Under Angles, enter 45 for A, 40 for B, and 95 for C. Then click Calculate. What happened? What message did the tool deliver? Explain the message in terms of the properties of a triangle and the given angles.
The tool gave an error message that read, “At least one side must be given.” This message appeared because an infinite number of triangles can be constructed with three valid angles (angles that sum to 180°). With the angle measures fixed, the sides of the triangle can increase and decrease in length to create an unlimited number of triangles. To construct a unique triangle, at least one side length of the triangle must be given along with the three angle measurements.
Explanation:
It was given to me when I submitted on Edmentum/Exact Path. :)
