What is it?
The section formula locates a point dividing a segment in a stated ratio; order of weights matters.
In simple words
- The section formula locates a point dividing a segment in a stated ratio; order of weights matters.
- Worked pattern: A point dividing A(0,0), B(6,3) internally in 1:2 is (2,1).
- Final check: domain, sign, notation, units, and reasonableness.
Important terms

Recommended for Class 12
Full school-level explanation
The section formula locates a point dividing a segment in a stated ratio; order of weights matters.
CONCEPT AND RULE
The section formula locates a point dividing a segment in a stated ratio; order of weights matters.
METHOD
For division of a line segment, identify the given information and required result. Select the matching definition or formula, state its conditions, substitute carefully, simplify one line at a time, and check.
WORKED EXAMPLE
A point dividing A(0,0), B(6,3) internally in 1:2 is (2,1).
COMMON MISTAKE
Write the governing rule before substitution, keep brackets and signs visible, and check that the answer satisfies all domain or interval conditions.
How to solve division of a line segment
How it works
- Identify the mathematical objects, givens, restrictions, and required result.
- Choose and write the relevant definition, theorem, or formula.
- Substitute with brackets and carry out one justified step per line.
- Simplify, state the final answer clearly, and verify it in the original setting.
