They are the vertices.
No... a quadrilateral is a figure of 4 sides. Trapzoid, square, diamond.... get the picture? A right angle is an angle. It is formed by two lines intersecting. They don't even necessarily make a shape.
An angle. A polygon is a plane figure bounded by straight sides (triangle, quadrilateral, pentagon, etc).
To be a polygon there has to be three or more sides. None of the sides can be curved or intersecting and the figure has to be closed.
A Vertex is a point in simple language
The common end point of the sides (or arms) of an angle is the vertex of the angle.
If a point is on the bisector of an angle, then it is equidistant from the two sides of the angle-apex
no
Every point on the bisector of an angle is equidistant from the sides of that angle. It is understood that the distance of a point from a line is the length of the perpendicular dropped from the point to the line.
