Circles In Geometry, Basic Introduction - Circumference, Area, Arc Length, Inscribed Angles & Chords
The Organic Chemistry Tutor・2 minutes read
The text explains the concept of circles, including the radius, diameter, circumference, area, sectors, arcs, chords, and inscribed angles with their respective formulas and relationships. It also discusses how to calculate different components of a circle using various measurements and angles.
Insights
- The radius of a circle is a line segment from the center to any point on the circle, while the diameter is a line passing through the center and is twice the length of the radius.
- When calculating the area of a sector in a circle, use the fraction of the circle's angle (theta/360) multiplied by the area of the circle; for arc length, it is theta/360 multiplied by the circumference.
