How many angles are formed when three lines intersect at three points?
Let three points be A, B & C.
Total angles subtened at point A = 4. (As shown in the figure)
Similarly, for point B and C.
Hence, total angles formed = (4 + 4 + 4) = 12
When three lines intersect at three points, how many angles are formed?
When three lines intersect each other at three different points, then how many angles will be formed?
