Yes, it is a vertex because the two lines meet.:):):):):):):):):)
L shape
If the a vertex forms a right angle which looks like this: 'L' that's is a right angle...sooo if there's a slope connecting the top of the L to the bottom of the L then it would be a right triangle....so in conclusion....as long as there's a vertex that forms a capital L somewhere then....it's a right triangle :)
The vertex angle is connected to the vertex point
A cube has no vertex
A circle does not have a vertex.
vertex
Vertex of a triangle is any of its 3 corners and the plural of vertex is vertices
A triangle is not a segment joining a vertex and the midpoint of the side opposite the vertex.
the vertex of the angle is the point
