Question

Find the angle between each lines, when five lines are drawn in "3-D" plane such way that the angles between them is equal.


Give full solution.

Answer 1

In 3D plane,

When all five lines are drawn in a single plane then,
figure will be like in above image...
(dotted lines are five lines)

360°/10 = 36°


There may be other possible case where all five lines are drawn in 3D space rather then 2D plane, then angle between them will be greater than 36°.
