☆☆☆☆☆A point has no dimensions. It can be drawn anywhere or marked anywhere.
A point is the one which cannot be measured.
all of them are collinear
they lie in the same plane
they lie in the same plane
lie on the same plane and are collinear
Yes, collinear points are also coplanar.
A line is one dimensional and can have infinite length.
Postulates and axioms are accepted without proof in a logical system. Theorems and corollaries require proof in a logical system.
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.
a ray and a line
No.
they are noncolinear if there are more than 2 points, if not then any two points always lie on the same line
A conclusion provided by deductive reasoning
It means "measure". So m<AVB is saying "the measure of Angle AVB is/= ? degrees".
The term that best describes a proof in which you assume the opposite of what you want to prove is 'indirect proof'.
