How many triangles can be drawn from 6 points where 4 of them are in straight line?
There are 16 possible triangles.
If six points lie on a circle how many quadrilaterals can be drawn joining these points?
5
What is the Name of the triangle formed by joining of points formed by the perpendiculars drawn from vertexes to the opposite side?
isosceles triangle
Why can all triangles tessellate?
because all triangles can be drawn with a compass
If all of the diagonals are drawn from a vertex of an n-gon how many triangles are formed?
If all of the diagonals are drawn from a vertex of an octagon, how many triangles are formed
What is the number of diagonls which can be drawn by joining the angular points of a polygon of 100 sides?
It consists of 98 triangles and has 4850 diagonals
How many lines can be drawn through three noncollinear points?
If you are talking about straight lines, the answer is NONE, because that is what noncollinear means. If curves are allowed, then the answer is infinitely many.
How many planes can be drawn through any three noncollinear points in a plane?
just one
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.
Are three noncollinear points always contained in only one plane?
Yes a plane can always be drawn three any three points, whether they are linear or not.
How many triangles can be drawn from 6 points where 4 of them are in straight line?
There are 16 possible triangles.
How many planes can be drawn through any three noncollinear points?
Only one plane can pass through 3 non-collinear points.
If six points lie on a circle how many quadrilaterals can be drawn joining these points?
5
Can three points be noncoplanar?
No, A plane can be drawn through any 3 points. If the 3 points are collinear then they make a line and a plane can contain a line. If the points are noncollinear then they can be used to form the corners of a triangle; all points of a triangle are in the same plane.
What was Euclid's first postulate?
A straight line segment can be drawn joining any two points.
What is the Name of the triangle formed by joining of points formed by the perpendiculars drawn from vertexes to the opposite side?
isosceles triangle
What is projection of line?
The line joining the feet of the perpendiculars drawn from all the points of the line onto a preselected plane.
