How do you decide whether or not the points are the vertices of a right triangle?

There are multiple ways.
One way would be to find the distance between each of the lines, and see if Pythagoreams Theorem would work (a^2 + b^2 = c^2).
Another way would be to find the length of the two lines that you think may be joining to form a right angle, and then seeing if Arc Tan (Side 1 / Side 2) + Arc Tan (Side 2 / Side 1) adds up to 90. (This works because the two non 90 angles in a right triangle will always add up to 90, because triangles have a total of 180 degrees, and a right angle is always 90 degrees.)
You could also graph it and use a protractor, but that is potentially very inaccurate.

What has only 3 vertices?
A triangle vertices are the end of a line; in a triangle there are only three such points.
Can any three points be the vertices of a triangle?
no
How do you count vertices in polygons?
The vertices refer to the points where to sides of a shape come into contact. So for example, a triangle has three vertices because its sides meet at three points. Each polygon also has the same number of vertices as sides (pentagon = 5 vertices, etc.)
What is Three points determine a plane?
If you were to have 3 points on the same line, then you would actually not be determining a plane, because there are infinitely many planes that can intersect a given line. But if you have 3 points in the form of the points (or vertices) of a triangle, then you determine a plane in the sense that there is only one possible plane upon which that triangle can be drawn (not including a degenerate triangle, which is equivalent to a line).
Difference between vertices and edges?
Vertices are points (corners) and edges are lines that connect vertices
What is a vertices of the triangle?
The apex Points of a triangle are called as vertices or else the points where two line segments meet is called as Vertices.
What were the “three points” of the triangle?
Vertices
What are the points of a triangle called?
Vertices.
What are corner points on a triangle?
vertices
What has only 3 vertices?
A triangle vertices are the end of a line; in a triangle there are only three such points.
Are the vertex and vertices of a triangle the same?
"Vertices" means "vertexes". "Vertex" means one of the triangle's points. The triangle has three points. When you talk about two or three of them, you're talking about 2 or 3 'vertices'.
Can any three points be the vertices of a triangle?
no
What is the name given to the three points of a triangle?
Its vertices.
The of a triangle is each of the three points joining the sides of a triangle?
Verticy, or vertices
How many points are in a triangle?
There are 3 points and they are called vertices which is the plural of vertex.
What are the required conditions of three points to be vertices of a triangle?
That they are not collinear.
What were the three points of the triangle?
Vertices
