A triangle is a figure formed by three segments and four coplanar points?
No. A trinagle does not require four points, three are sufficient. And any three points, if they are not colinear, must be coplanar.
Do three coplanar points lie on the same line?
They lie in the same plane, but they don't necessarily have to lie on the same line. Every triangle consists of three points that are coplanar but non-colinear.
What is a closed plane figure with at least three sides that are segments which only intersect at their endpoints and have no two adjacent sides that are coplanar?
a triangle
What is the difference between coplanar and non-coplanar vectors?
Coplanar :The vectors are in the same plane.Non coplanar :The vectors are not in the same plane.
What is similar between collinear and coplanar points?
because coplanar is coplanar and collinear is collinear!!
Can two line segmeant be coplanar?
Yes, of course, two line segments can be coplanar: Think of the sides of a plane triangle.

No. A trinagle does not require four points, three are sufficient. And any three points, if they are not colinear, must be coplanar.
What is a counterexample for three coplanar lines always make a triangle?
If at least two of the three lines are parallel, the three lines will not form a triangle.
What is a plane figure formed by coplanar segments?
It is a plane figure, for example, a semicircle, a triangle, a kite.
What are lines that lie in the same plane?
They are coplanar. ANY 2 lines would be coplanar, however a third line can be outside of the plane. just like 3 points will designate a plane and a triangle
Do three coplanar points lie on the same line?
They lie in the same plane, but they don't necessarily have to lie on the same line. Every triangle consists of three points that are coplanar but non-colinear.
Are four noncollinear points always coplanar?
No. For example, consider the vertices of a tetrahedron (triangle-based pyramid).
Difference between concurrent coplanar forces and non concurrent coplanar forces?
Concurrent coplanar forces have their lines of action intersecting at a common point, allowing them to be resolved using the parallelogram law of forces. Non-concurrent coplanar forces have their lines of action not intersecting at a common point, requiring the use of the triangle law of forces for resolution.
What is a closed plane figure with at least three sides that are segments which only intersect at their endpoints and have no two adjacent sides that are coplanar?
a triangle
What is the difference between coplanar and non-coplanar vectors?
Coplanar :The vectors are in the same plane.Non coplanar :The vectors are not in the same plane.
What is similar between collinear and coplanar points?
because coplanar is coplanar and collinear is collinear!!
Differentiate coplanar from non coplanar?
coplanar are points that lie on the same plane meanwhile non coplanar are points that don't lie on the same plane.
