no coliner points donot make triangle
Three non-collinear points do not determine a unique spherical triangle.
a right angled triangle is special because it is the only triangle that has a right angle with a dregree of 180.
A triangle can't be a square. A triangle only has 3 points, squares have 4.
vertices
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.
a triangle has 3 points
Three non-collinear points do not determine a unique spherical triangle.
a right angled triangle is special because it is the only triangle that has a right angle with a dregree of 180.
The answer depends on what is special about the triangle and what else you know about it.
The points in a triangle has to be 180 degrees to be a triangle.
A triangle can't be a square. A triangle only has 3 points, squares have 4.
The special thing about an equilateral triangle is that all sides are the same length and all three angles are 60 degrees. It is a special case of the isosceles triangle.
A right triangle is right-angled (one angle = 90º) but none are "special".
