It's not possible to draw two points that aren't on the same straight line.
draw two angles in three common points
No. To prove this, you can actually construct the plane.
Is false
Three points determine exactly one plane.That means that if you bring me a plane, then some or all of my three points may ormay not lie in your plane. But if you bring me three points, then I can always draw aplane in which all of your points lie, and I can also guarantee that it's the only one.By the way ... three points also determine exactly one circle.
To connect seven noncollinear points, draw six line segments connecting each point to every other point. This will create a network of lines that connect all seven points without crossing or overlapping.
point B lies in plane U
It's not possible to draw two points that aren't on the same straight line.
as in a 7 sided figure? a heptagon
It depends on the figure. For example, you cannot draw a net for a sphere, an ellisoid or a torus.
a nonagon
three
if i put three points on the common arm ,then they are common points for both the two angles
It is the circumcentre of the triangle formed by the three points. Draw the perpendicular bisectors of two of the lines joining the three points. They will meet at the point that is equidistant from the three points.
draw line of symmetry for 20
draw two angles in three common points
Take the 4 corners (vertices) of any 4-sided figure (quadrilateral). Draw the quadrilateral and its diagonals.
