Clearly the number of possible questions is endless but examples are:
Find the opposite (side to the 41 degree angle)
Find the adjacent
Find the other angle of the triangle
Find the area of the triangle
Find the radius of a circle that has the same area as this triangle
Find the length of the opposite in inches

How many of these triangles would it take to tessellate a rectangular area 2 metres by 3 metres?
