Angles in Circles
Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made perpendicular to the radius through its endpoint placed on the circle as well as the line drawn at right angles to a tangent across the point of contact when the circle passes through the center of the circle. The chord is a line segment with its endpoints on the circle. A secant line or secant is the infinite extension of the chord.
Arcs in Circles
A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.

![The department of public safety has an old memo stating that the number of accidents per week at a hazardous intersection
varies according to a Normal distribution, with a mean of 2.2 and a standard deviation of 1.4. Department officials
implemented a new safety plan, heavier police patrols and new signs, to see if they could reduce the average number of
accidents at this intersection. They recorded the number of accidents per week for 52 weeks. They find that the average over
that period was two accidents per week.
