Circumcenter, incenter, orthocenter and centroid.
The centroid
The following is the answer.
no
The are the intersection points of the line segments that make up the sides, in other words the corners of the triangle.
A triangle vertices are the end of a line; in a triangle there are only three such points.
When three or more lines intersect at one point, then they are considered concurrent.The four points of concurrence in triangles are the circumcenter, incenter, centroid, and orthocenter.
The centroid
No. A trinagle does not require four points, three are sufficient. And any three points, if they are not colinear, must be coplanar.
An isosceles triangle has two sides of equal length and the angles opposite those sides are also equal. The term "coplanar" means that four points lie on the same plane. In the context of an isosceles triangle, the three vertices of the triangle and any additional point (such as the midpoint of the base) can indeed be coplanar. Therefore, it is true that four points can be coplanar in relation to an isosceles triangle.
The medians of a triangle are concurrent and the point of concurrence, the centroid, is one-third of the distance from the opposite side to the vertex along the median
Equilateral.

No. For example, consider the vertices of a tetrahedron (triangle-based pyramid).
The complement of the triangle in the plane.
The following is the answer.
no coliner points donot make triangle
A triangle with VERY round points is a circle. There is no geometric term for a triangle with rounded points, but a triangle with rounded sides is known as a Reuleaux triangle. It is similar to the shape used for the piston in a rotary engine.
