 # Question: How Many Straight Lines Can Be Drawn From A Point?

## How many lines can be drawn passing through three points which are not in a straight line?

1 lines can be drawn through three collinear points and 3 lines from non collinear points​.

## How many diameters can be drawn in a circle?

So, you can only draw one diameter per circle since that circle only has one diameter. How can you calculate a circle diameter without being able to measure it through its center?

## How many points can be on a line?

two pointsA line is defined by two points and is written as shown below with an arrowhead.

## How many triangles are formed?

The number of triangles is 1, 8, 35, 110, 287, 632, 1302, 2400, 4257, 6956 for polygons with 3 through 12 sides. If we connect all vertices of a regular N-sided polygon we obtain a figure with = N (N – 1) / 2 lines. For N=8, the figure is: Careful counting shows that there are 632 triangles in this eight sided figure.

## How many minimum points are required to draw a straight line?

two pointsMinimum two points are required to form a line. Single point can form Ray but not a line.

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

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

## Can parallel lines intersect?

Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect.

## What do you call a figure formed by two straight lines having a common point?

TriangleThe figure which is formed by two straight lines having a common point is called a Triangle. A triangle is a mathematical shape with three vertices and the same number of angles. A triangle is a 2D shaped polygon.

## 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 triangles can be drawn through n points on a circle?

But clearly, it is more of a combination problem. How many triangles can be formed from N given points. Since the points on the circle cannot be colinear, we can chose any three independant points from a given set of “N” points.

## How many lines can 3 draw?

(iii) Only one line can be drawn through three collinear points.

## How many lines can you draw using 3 non collinear not in a single line points a B and C on a plane?

The lines are: AB, BC and AC ; 3 lines only. So in fact we can draw 3 lines and not 6 and that’s because in this problem the order of the points A, B and C is not important.

## How many minimum points are required to draw a unique straight line?

two pointsTo draw a straight line the minimum number of points required is two. Given any two points, a straight line can be drawn.

## How many chords can be drawn 21 points?

210 chordsTherefore, 210 chords can be drawn through 21 points on a circle.

## How many chords are in a circle?

Chords and regions 2 chords divide a circle into 4 regions.

## How many lines can pass through 4 non collinear points?

Answer: Six is the correct ans.

## How many lines are between two points?

1 Expert Answer Only one line segment can be drawn between two points. Any other line segments would be overlapping and the same segment.

## How many points is enough to fix lines?

Two pointsTwo points are enough to fix a line.

## How many triangles form 12 non collinear points?

1 Answer. If no three points in the set are collinear, then similarly we can choose any two points other than A to be other two vertices of a triangle. Hence the answer is C(11,2).

## How many triangles can be formed from 9 points?

Total number of ways are: (93)=84.
