Write a C++ program to analyze a variety of triangles. The program should determine all angles and all sides for a triangle for three different options (give the user a menu of choices): Given two sides and the angle between First check to be sure that the three values entered are valid. In particular, the following conditions must be met: Both sides > 0 If angle is in degrees, then 0 < angle < 180 (if angle is in radians, convert it to degrees first and then check)
