Question 52 Marks
What do you mean by collinear points?
- How many lines can you draw passing through three collinear points ?
- Given three collinear points A, B, C. How many lines segments do they determine? Name them.
Answer
View full question & answer→- Three or more points in a plane are said to be collinear if they all lie on the same line.
- In the figure given above, points A, B, C are collinear points. We can draw exactly one line passing through three collinear points
