On one straight line , there are
non-A points, and on another straight line
, there are
non-A points. With these places serving as vertices, how many triangles may be constructed? How many possibilities are there if point
is also considered?
A triangle has three vertices, hence picking two points on one line, one on the other, and vice versa.
Consider the scenario where one of the triangle's points is the intersection of two lines.
Two points and one
point can be combined to form a triangle, as can one
point and two
points.
The outcome is that there are now more triangles.
More triangles can be obtained if point is included. As a result, in this case,
Option c) is correct.
