Quick Answer: How Many Straight Lines Are Determined By 8 Points?

How many straight lines can be drawn through a point?

(i) Only one line can pass through a single point.

(ii) There are an infinite number of lines which pass through two distinct points..

How many lines is 4 distinct points?

Since two points determine a line and there are 4 points (and no 3 of them are collinear), the number of lines that can be created is 4C2 = (4 x 3)/2! = 6.

How many lines is two distinct points?

Only one line can pass through two given points.

How many lines are determined by four non collinear points?

Answer: Six is the correct ans.

How many lines are determined by n points?

If there are n points, the answer is n-1. This is how many lines can pass through that first point and another point at the same time. Continuing with the above example, A can be matched up with B or C or D or E or F or G or H. That’s seven possible matches.

How many straight lines are there?

Straight lines are classified into three types, viz. standing/vertical lines, sleeping/horizontal lines and slanting/oblique lines.

How many lines are determined by 3 non collinear points?

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

How many straight lines can be drawn through two given lines?

1 straight lineOnly 1 straight line can be drawn through two given points.

How many triangles can be formed with 10 points in a plane of which no three points are collinear?

120 Triangles120 Triangles Can be formed with 10 points in which no three points are colinear.

How many straight lines can be formed by 8 points of which are collinear?

Also using this fact, we cannot cut the line in any point because it will already create two rays. Note that a ray is an infinite line but only extends in one direction, meaning it has only one end point. Therefore, there can only be one straight line that can connect 8 collinear points.

How many straight lines can be drawn by joining 10 points on a circle?

The number of ways to select any points (out of 10 distinct points) will be 10C2. Once we select the points, there is only 1 straight line which will be formed using these points. Therefore the number of lines will be 10C2 x 1 or 45. Here’s a crazy figure to illustrate.

How many lines is three distinct points?

three linesSo, we can name the lines as AB, BC and AC. Hence, we get that only three lines are possible with the help of three distinct points.
