When 2 or more straight lines meet...the point where they meet is called the point of intersection
The point where the x-axis and the y-axis meet is called the origin.
That point, (0,0) is called the origin
A vertex is a point where two line segments or rays meet. For example: a triangle could have 3 possible vertexes, but many more points. The points are not only where two lines meet, but any where on that line, ray, or shape.
The name of the starting point when plotting points on a graph is called the point of origin. It is located on the point (0,0) or where the x and y axes meet.
The focal point?
At a point, which is called a vertex.
Tangent.
a vertex or vertice(s)!
< the point where the two rays meet is called a vertex.
vertex
An image is called real if the light rays coming from a point(point on object) meet at a point after reflection or refraction. An image is virtual if the light rays do not actually meet after reflection or refraction. These rays appear to come from a point which is the point where we say virtual image is formed.
This is the focal point, the point of focus.
At a point/vertex.
the vertex
A focal point is the point where reflected light rays meet along an optical axis.
It's true, an angle is made up of two rays. Two rays meet at a point, and their relative position at the point where they meet will define an angle.
