Question

Length of projection of line segment on plane formula

Answer 1

Answer:

If a, b, c are the projections of a line segment on coordinate axis then the length of the segment = √(a2 + b2 + c2) If a, b, c are the projections of a line segment on coordinate axis then its dc's are ± a/√(a2 + b2 + c2), ± b/√(a2 + b2 + c2), ± c/√(a2 + b2 + c2)

I hope this will help uhh
