Dec 31, 2020 · 7.1: Regular Polygons. A regular polygon is a polygon in which all sides are equal and all angles are equal, Examples of a regular polygon are the equilateral triangle (3 sides), the square (4 sides), the regular pentagon (5 sides), and the regular hexagon (6 sides). 7.2: Circles.

The word ‘circle’ is derived from a Greek word that means ‘hoop’ or ‘ring.’ In geometry, a circle is defined as a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center.” Never confuse a circle with a polygon. A circle is not a polygon because it is made up of curves. The histo...
Center: The center is the midpoint of a circle. In the above diagram, the center of the circle point ‘O’.Radius: This is a line segment from the center of a circle connecting any point on the circle itself. The radius of a circle is denoted by either letter “r” (lower case) or “R” (upper case).There exist several facts about circles. These facts about circles are known as the properties of the circle. Let’s examine them. 1. Circles with equal radii or diameters are congruent. 2. The longest chord of a circle is called the diameter. 3. The diameter of a circle is twice the radius of the circle itself. 4. The diameter divides the circle in...
Nov 11, 2024 · To ponder this, we’ll continue down the path of hypothesis two, that a circle is a polygon or at least a closed structure with an infinite number of sides. In this definition of a circle, we can consider each individual point that makes up the circle to be a side.
A circle is a 2-dimensional closed shape that has a curved side whose ends meet to form a round shape. Learn about circles with concepts, properties, and examples.
A circle is a locus of all the points equidistant from a fixed point to the outer boundary. Learn its definition, construction of the circle, formulas for area and circumference with solved examples.
A circle is a round-shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed shape, two-dimensional shape, curved shape. A few things around us that are circular in shape are a car tire, a wall clock that tells time, and a lollipop.
A polygon is a plane shape (two-dimensional) with straight sides. Examples include triangles, quadrilaterals, pentagons, hexagons and so on. Regular. Here we look at Regular Polygons only. Properties. So what can we know about regular polygons? First of all, we can work out angles. All the Exterior Angles of a polygon add up to 360°, so:
