What is a convex polygon and an example?
A convex polygon is one whose internal angles measure equal to or less than 180º. Thus, all its diagonals are inside in the figure. Also, it is worth mentioning that the triangle is the only polygon that is always convex because its interior angles must add up to 180º. …

What is a polygon inscribed in a circle?
Inscribed polygons, a polygon inscribed in a circumference is one that is enclosed in the circumference, all its vertices are on the circumference itself and its sides are chords. Remembering String. It is a segment that joins two points on the circumference, for…
What is the diameter of a circumference?
It is a segment that joins two points on the circumference, therefore, the diameter is the chord of maximum length. The perpendicular bisector of any chord of a circle passes through the center of the circle. To build a (regular) decagon inscribed in a circle, we need to know the radius of the circle.
What is the radius of the circumference?
To construct a (regular) decagon inscribed in a circle, we need to know the radius of the circle. In the following example, the radius of the circle will be the radius AB.
