If they are coplaner
Parallel
they are two or more forces on the same plane
1) point 2) line 3) coplaner
equilbrium in coplaner forces at rigid body.
coplaner
Coplaner means all points, lines, circles, vectors etc. lie in a single (usually theoretical) flat plane.
If they are coplaner
Parallel
Yes, they are.
I dont think that "If four points are collinear they are also coplaner," is the same thing as "If four points are coplaner they are also collinear,". The definition of collinear is at least three points on the same line. To define a plane is to have threenoncollinear points.
Yes.
coplaner points- are points lying on his the same plane,.. solution: plane R contains XY XY contains X and Y...
they are two or more forces on the same plane
Yes. If they're not parallel, then they mustintersect.
if they are parallel -- no. if not parallel -- yes
