How many rays can be formed with 8 collinear points?
14
How many line are determine by eight points if none of three points are colinear?
You've basically asked "what is 8 choose 2?", which is 8! / ( 6! * 2! ) or 28. The two are identical because each pair of points determines a line (since no three points are collinear). Since there are 28 ways to choose 2 items from a set of 8 items, there are 28 possible pairs of points and therefore 28 lines.
How many line segments in a 9 points?
THe maximum number of lines that can be achieved between 9 points is 8+7+6+5+4+3+2+1=36.
The locus of points equidistant from the lines y equals -2 and y equals 8?
The locus of points between 2 lines will always be another line that is halfway between the original 2 lines. In this case, that will be a line halfway between y=-2 and y=8, and since 3 is halfway between -2 and 8, the locus will be the line y=3.
Which type of lines pass through points (2 5) (8 7) and (-3 1) (-2 -2) on a grid?
Mutually perpendicular lines.
How many different rays can be formed from five collinear points?
One! That is what collinear means!
How many rays can be formed with 8 collinear points?
14
How many triangles can be formed out of 8 non collinear points?
64 triangles
Find the number of diffrent segments formed by 8 collinear points?
8 collinear points determine 28 unique line segments

How can you connect 25 dots with 8 lines?
It depends on where the dots are located. If they are all collinear only one straight line is required. For a 5x5 grid, only 5 lines are required.
How many lines of symmetry does a regular octagon have?
It has 8. Each passes through the centre. Four pass through vertices, four pass through the mid-points of opposite sides. 4
How many line segments in a 9 points?
THe maximum number of lines that can be achieved between 9 points is 8+7+6+5+4+3+2+1=36.
How many lines of symmetry are there on a regular octagon?
8. 4 between the opposite vertices 4 between the mid points of opposite sides.
How many points is shrimp cocktail?
8 points.
How many triangles can you make on a 3X3 grid?
The correct answer is 76. There are 9 points in the grid. You can pick any 3 out of these 9 points in 9*8*7/(3*2*1) = 84 ways. However, 3 will form horizontal lines in the grid, 3 will form vertical lines in the grid, and 2 will form diagonal lines in the grid. None of these 8 triplets will form triangles, but all the rest will. So the answer is 84-8=76.
How many paralell lines does a octagon have?
It has 8 parallal lines:)
