CBSE Class 12-science Maths Skew Lines
Score marks in questions related to CBSE Class 12 Science Mathematics – Three-Dimensional Geometry – Skew Lines with TopperLearning’s support. To understand skew lines, you need to learn about the angle between two lines. Also, learn to calculate the shortest distance between two lines. Our Mathematics expert will help you understand the distance between two skew lines and the distance between two parallel lines with suitable examples.
Revise problems on finding the shortest distance based on the given equations in our CBSE Class 12 Science Mathematics textbook solutions. Also, practise the Three-Dimensional Geometry questions in our practice tests and solved question papers for improving your Maths skills.
- Find the angle between two lines whose directions cosines are given by l+m+n=0 and l^2+m^2-n^2=0.[**WITHOUT USING THEOREMS OF VECTOR**]
- Find the shortest distance whose equations are r = (i-j) + lambda(2i+k) and r= (2i-j) + mu(i+j-k)
