![Find the no. of triangles and please name them][1]
John is selling fruits. He sells grapes at $30, Dates $25, and a Wolfberry $45. At what price does he sell fig?
PS: Logical Idea
How many triangles are there in a regular pentagon with all its diagonals drawn?
Note: a regular pentagon has five straight sides all of the same length and five equal angles. A diagonal is a line joining points.
