What else can I help you with?
Ten points are marked on a straight line and eleven points are marked on another straight line How many triangles can be constructed with vertices from among the above points?
1op2*11+11p2*10
There are nine points in a plane. No three points are in the same straight line. How many different triangles can be formed by using the nine points as vertices?
84
If points A B and C all lie in a straight line but the other points are not on the line how many different lines can be drawn if each line contains at least two points?
2 lines, I believe.
Which line ray or line segment is drawn from a triangles vertex to midpoint of the opposite side?
the median is drawn from the vertex to the midpoint of the opposite side
What is a Chords in circles?
A chord is a straight line drawn through a circle which divides the circle into two parts. The line can be drawn anywhere in the circle EXCEPT the center where it becomes the diameter.
Given n points in the plane you draw all possible triangles whose vertices are any three of the given points Atleast how many of them are obtuse-angled triangles?
The least number of obtuse triangles, if all possible triangles are drawn for n points in a plane, is zero. If all the n points lie in a straight line, no triangles are possible and so no obtuse triangles are able to be drawn; thus for any number n, there is a possibility that no obtuse triangles can be drawn, so the least possible number of obtuse triangles drawn is zero.
Ten points are marked on a straight line and eleven points are marked on another straight line How many triangles can be constructed with vertices from among the above points?
1op2*11+11p2*10
How many straight lines can be drawn through two points?
i think just one line, as its defenition of straight line
How many planes can be drawn when three distinct points are collinear?
If the points are collinear, that means there's only one straight line. An infinite number of different planes can be drawn that contain one straight line.
What the name of straight lines that can be drawn through one points?
line segments

What was Euclid's first postulate?
A straight line segment can be drawn joining any two points.
If points A B and C all lie in a straight line but the other points are not on the line how many different lines can be drawn if each line contains at least two points?
2 lines, I believe.
What is the number of straight angles that can be drawn through two points?
Angles on a straight line add up to 180 degrees.
How many lines can be drawn through 2 points?
1 straight line. An infinite number of curved lines.
How many line segments can be drawn from two points?
There is only one line (or line segment) that can be drawn between two distince points.
By distance formula how you can show that -1423and81 are collinear?
If you only have two points, they are necessarily collinear, because a straight line can be drawn between any two points.
