Triangles in a Circle
8 points are spaced around the boundary of a circle and all chords are drawn between them such that no three chords intersect in a point that is not on the circumference. How many different triangles can be seen in the resulting figure?
Details and assumptions
A triangle can be seen in the figure if all 3 sides are segments of the drawn chords.
As an explicit example, when there are \(4\) points, we have 8 triangles, namely \( ABC, BCD, CDA, DAB, EAB, EBC, ECD, EDA \), as seen below.
