Is the radius the same as the side length on a regular polygon?
But in geometry, we also use the term ‘radius’ for regular polygons – those where all the sides and interior angles are equal. The radius of a regular polygon is the distance from its center to any one of its vertices.
Are an Apothem and radius the same?
The radius of a regular polygon reaches from its center to any vertex, bisecting the angle at that vertex. The apothem reaches from the center to the midpoint of any side. It always bisects the side and is always perpendicular to it.
How do you define a regular polygon?
A polygon is called regular if it has equal sides and angles. Thus, a regular triangle is an equilateral triangle, and a regular quadrilateral is a square.
Do polygons have a radius?
The distance from the center to a vertex (corner point) of a regular polygon. It is the radius of the circle (called the circumcircle) that passes through all vertices (corner points) of the regular polygon.
What is diagonal of a polygon?
Polygons. As applied to a polygon, a diagonal is a line segment joining any two non-consecutive vertices. Therefore, a quadrilateral has two diagonals, joining opposite pairs of vertices.
Is the radius of a regular Pentagon equal to the side length?

What is the apothem of a regular polygon?
The apothem (sometimes abbreviated as apo) of a regular polygon is a line segment from the center to the midpoint of one of its sides. Equivalently, it is the line drawn from the center of the polygon that is perpendicular to one of its sides. The word “apothem” can also refer to the length of that line segment.
Can a regular polygon have an apothem and a radius of the same length?
Definition: A line segment from the center of a regular polygon to the midpoint of a side. The apothem is also the radius of the incircle of the polygon. For a polygon of n sides, there are n possible apothems, all the same length of course.
What is a diagonal of a polygon?
A more general definition of a diagonal of a polygon is a line segment that joins two vertices of the polygon which are not already joined by an edge of the polygon.
Which of these is a regular polygon?
A regular polygon is a polygon with congruent sides and equal angles. The examples of regular polygons include equilateral triangle, square, regular pentagon, and so on.

What is radradius (polygon)?
Radius (Polygon) more The distance from the center to a vertex (corner point) of a regular polygon. It is the radius of the circle (called the circumcircle) that passes through all vertices (corner points) of the regular polygon.
What is radius in physics?
radius – the length of a line segment between the center and circumference of a circle or sphere. r. diam, diameter – the length of a straight line passing through the center of a circle and connecting two points on the circumference.
What is circum circle of a regular polygon?
In a regular polygon all its vertices lie on a circle. This circle is also called the circumcircle. Circumcircle of a regular polygon Being equilateral is not enough
