∙ 7y agoAn incident ray that passes through the vertex of a convex lens will continue in a straight line without being refracted. This is because the lens is thinnest at the vertex and has minimal effect on the path of light passing through this point.
The principal axis of a mirror is an imaginary line that passes through the center of curvature and the vertex of the mirror. Light rays parallel to the principal axis either converge or diverge after reflecting off the mirror.
The center of curvature of a mirror is the point located at a distance equal to the radius of curvature from the mirror's vertex. It is the center of the sphere of which the mirror forms a part. Light rays that are reflected from the mirror and pass through this point are either parallel to the principal axis (for concave mirrors) or appear to diverge from this point (for convex mirrors).
Well first off, convex mirrors are diverging mirrors, which means when they reflect light rays, the light rays never meet. The image that forms when an object is any length away from the mirror, the image is VIRTUAL and erect, the height of the image is smaller than that of the object, and the image is always between the focal point and the vertex of the mirror. Hope that helped!
The vertex of a concave mirror is the point where the principal axis intersects the mirror's surface. It is the point where the mirror's curvature is maximum and is typically located in the middle of the mirror. The vertex is an important reference point for understanding the mirror's focal length and properties.
The path of the light ray that hits a mirror at its vertex will reflect back along the same path, perpendicular to the mirror surface. This is known as the law of reflection, where the angle of incidence is equal to the angle of reflection.
A median of a triangle is a line or segment that passes through a vertex and bisects the side of the triangle opposite the vertex.
A median of a triangle is a line or segment that passes through a vertex and the midpoint of the side opposite that vertex. The median only bisects the vertex angle from which it is drawn when it is an isosceles triangle.
The segment that passes through a vertex and is perpendicular to the opposite side is called the altitude of the triangle.

These terms describe polygons. To identify a polygon as convex, we draw a segment from any vertex to any other vertex. This segment cannot go outside of the polygon. Non-convex is concave. If we draw a segment from a vertex to any other vertex, at least one of the segments will go outside of the polygon.
please help
A line through the vertex and the side opposite - nothing more. There need not even be a side opposite - as is the case with a square!
and is perpendicular to the opposite side.
median
It is a straight line which passes through the vertex of the angle and divides it into halves.
