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.
