What is a circle?
A circle is the locus of points equidistant from a given point called the center of the circle.
A circle can be described if its radius and the center of the circle is known.
Analysis:
1. RCH is called a semicircle when a diameter divides a circle into two equal parts, a part is called the semicircle.
2. ∠RAH is the central angle, because it is the angle subtended at the Center of the circle.
3. CA is the radius of the circle, a line drawn from the center to any point on the circumference of the circle.
4. MR is a secant, a line that cuts the circle into two parts.
5. A is the center of the circle.
6. MT is the tangent, because line MT touches the circle at a point T.
7. CH is the diameter of the circle, a line that divides the circle into two semi circles.
8. CT is the minor arc, the curved line that is found in the smaller part of the divided circle.
9. HT is chord, it is a line that divides the circle into two unequal parts.
10. CRH is major arc, the curved line of the bigger portion of the divided circle.
