An angle can be defined as two rays or two line segments having a common end point. The endpoint becomes known as the vertex(shared endpoints). An angle occurs when two rays meet or unite at the same endpoint.An angle can be identified as ABC or CBA. You can also write this angle as B which names the vertex (common endpoint of the two rays)The vertex (in this case B) is always written as the middle letter. It matters not where you place the letter or number of your vertex, it is acceptable to place the it on the inside or the outside of your angle.You can also name the vertex by using a number. For instance, B could also be named angle 3 if you choose to change the letter to a number. Angle ABC or CBA would be names A3C or C3A or 3.

have the same vertex. be congruent.

A dodecagon has 12 sides. Whether or not from one vertex, the number of sides remains the same. Each vertex is formed when 2 sides meet.

Yes, it is. Circles that are in the same plane and having the same center are called congruent circles.

The median is a line from a vertex to the midpoint of the opposite line and an altitude is a line from a vertex to the opposite line which is perpendicular to the line. These are NOT the same thing in most triangles. The only time they could be the same is in an equilateral triangle.

They can have the same vertex - if that is what the question was about.

An angle.A vertex is the common endpoint of two rays. Vertex typically means a corner or a point where lines meet. For example a square has four corners, each is called a vertex.No, its an angle, not a vertex. I promis:)

An angle is formed when two rays begin at a common point. The common point is called the vertex of the angle.

yes of coures

an angle

Extend both rays beyond the other side of the vertex.

a right angle

common point of two rays or lines, note: rays and lines are the same thing!!

They form a vertex because they are line segments. An angle is two rays with the same point

The vertex of an angle

Two collinear rays with the same endpoint form an angle. They share a common initial point and extend in opposite directions. The endpoint where they meet is called the vertex of the angle.
