If three lines intersect at three points, 12 number of angles are formed?
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?
If two lines intersect and one of the angles so formed is a right angle, then the other three angles will not be right angles.
