Circle and its degrees

WebThe major arc of a circle is an arc that subtends an angle of more than 180 degrees to the circle’s center. Is the central angle half the arc? The inscribed angle theorem states that an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle. Therefore, the angle does not change as its vertex ... WebA car travels around a circular track clockwise (as viewed from above) at constant speed. Its initial position is at the northern end of the circle, and its final position is at the southern end of the circle. The radius of the track is 500 m, and it took the car 50 seconds to travel from its initial position to its final position.

The value … Apollonius of Perga showed that a circle may also be defined as the set of points in a plane having a constant ratio (other than 1) of distances to two fixed foci, A and B. (The set of points where the distances are equal is the perpendicular bisector of segment AB, a line.) That circle is sometimes said to be drawn about two points.

Find the measure of the missing angles x and y in the diagram below. Solution. x = 80 o (the exterior angle = the opposite interior angle). y + 70 o = 180 o (opposite angles are supplementary). Subtract 70 o on both sides. y = 110 o. Therefore, the measure of angles x and y are 80 o and 110 o, respectively. how to remove links from watch band citizenWebWe know that a reflex angle and its corresponding angle add up to 360°.
