an angle
Start by drawing a horizontal line. Next place a dot near the middle of it where you want the vertex. Then draw a 20° angle upward and to the right using your dot as the vertex, and the horizontal line as one leg of your angle. You can then erase (if you want) the horizontal line that forms one side of your 20° angle Your 200° angle then extends from the horizontal line to the left of the vertex counterclockwise around to the remaining leg of your 20° angle.
an angle.
In 2 dimensional space, a vertex is formed when two lines meet at an angle. In 3D space, a vertex is a point where three or more faces meet.A sphere is not an arced line but is one curved surface. It has no vertex.
