How many lines are determined by 5 points No 3 of which are collinear?

Total eight lines. Actual number of line drown by 5 point out of which 3 points are collinear is 7 .

How many lines can form from 5 collinear points?

Answer: Given 5 points, a line consist always of 2 points. Thus the total number of straight lines that can be drawn between 5 points is 5_C_2 = 10.

How many lines can be drawn from 10 given points No 3 of which are collinear?

So, number of lines is 9×10 or 90.

How many straight lines can be drawn by joining 20 points?

Answer: (4) 185 Solution: Given, 20 points out of which 4 are in same line. Selecting both the points from 4 points that are collinear, we get a single line.

How many lines can 3 Noncollinear points draw?

Four lines can be drawn through 3 non-collinear points.

What are the 3 collinear points?

Three or more points that lie on the same line are collinear points . Example : The points A , B and C lie on the line m . They are collinear.

How many planes contain the same 3 collinear points?

one plane
Three collinear points lie in only one plane. 4. Two intersecting lines are contained in exactly one plane.

How many points in a plane of which 5 are collinear?

There are 12 points in a plane of which 5 are collinear. Find (i) the number of straight lines obtained by joining these points in pairs (ii) the number of triangles that can be formed with vertices at these points. There are 12 points in a plane of which 5 are collinear.

How many points are there in a plane?

There are 10 points in a plane, no three of which are in the same straight line excepting 4 , which are collinear. Then number of There are 10 points in a plane, no three of which are in the same straight line excepting 4, which are collinear. Then number of

How many triangles can be formed from 6 non-collinear points?

To form a triangle we require 3 non-collinear points. As we have 6 non-collinear points, we have to choose 3 out of 6. We can, therefore, make 20 triangles from 6 non-collinear points. , Math-o-phile! There are 15 points on a plane out of which 10 are collinear .how many triangles formed by joining these ponts?

What is the coordinate of the 3rd collinear point?

Since the points are collinear the slopes for these two points are equal so, Thus, the value for k is 10 and the coordinate of the 3 rd collinear point is (5, 10). 4. There are only 2 vertices that are collinear for any convex polygon in the plane.
