False. Three collinear points determine a line while three non-collinear points determine a plane ( A Triangle)
Any three points anywhere in space can be the vertices of a triangle, as long as all three are not colinear.
False.
It has 3 sides.every tryangle has three sides and three verticies no matter what kind it is
First, I'm assuming the by corners, you mean verticies. Second, the answer depends on what you mean by "three dimensional triangle. To some, this could be interpreted as a pyramid. However, I think it is more likely that you are referring to a triangular prism- a prism shape with a triangle as each base. In this case, there are six "corners". Each side has three, where the length-wise edges of the prism intersect the verticies of the triangle. There are three corners on each side, for a total of six. If you really meant a pyramid, then there are five corners.
The statement is false. An isosceles triangle has at least two sides that are congruent, not necessarily three. A triangle with three congruent sides is called an equilateral triangle, which is a specific type of isosceles triangle.

No. Not if they are collinear (on the same straight line).
False.

It's called a "triangle". All of them have three points.
Vertices
Yes, three points can fail to form a triangle if they are collinear, meaning they all lie on the same straight line. In such a case, the points do not enclose any area and do not create the necessary three sides that define a triangle. However, if the points are not collinear, they will always form a triangle.
The three points in the fire triangle are fuel, heat and oxygen. To stop a fire you need to take one of those elements away from the triangle :)
