Angle E is the vertex.
A vertex is the same as an angle. A decagon has 10.A vertex is the same as an angle. A decagon has 10.A vertex is the same as an angle. A decagon has 10.A vertex is the same as an angle. A decagon has 10.
Acute: 0 < X < 90; Right: = 90; Obtuse: 90 < X < 180; Straight: = 180; Reflex: 180 < X < 360. The Acut, Right, Straight and Reflex are actually classifications of an angle. Naming of an angle is done by identifying the vertex and a combination of the vertex and points on the two rays. For example an angle with points ABC where B is the vertex and A and C are points on the accompanying rays may be named as angle B, angle ABC or angle CBA. These can be written with the symbol for angle placed before the B the ABC and the CBA.
any angle

It is a straight angle.
A straight angle has 180 degrees. It is an angle that has sides in opposite directions from its vertex. A straight angle will look like a straight line.
An angle comprises to rays meeting at a vertex. An angle bisector is a straight line through the vertex which bisects the angle.
If you mean an angle then an angle is formed by two straight lines meeting at a vertex.
It is a straight line which passes through the vertex of the angle and divides it into halves.
Not sure about straight angels, but a straight angle is simply a straight line which goes through the vertex.
The sum of an adjacent interior and its exterior angle will total to 360°. If the angles were to be equal, they would both have to be 180°. An angle of 180° is a straight line. A polygon may be composed of straight lines that intersect at vertices but a straight line has no vertex. That being the case, the answer to your question is "No".
A right angle joint is called a vertex as is with any other angle (yes even straight angles)
the vertex of the angle is the point
vertex angle
The vertex angle is connected to the vertex point
