Answer 1

Answer:

1. The center of a circle is the point equidistant from the points on the edge. Similarly the center of a sphere is the point equidistant from the points on the surface, and the center of a line segment is the midpoint of the two ends.
2. A chord of a circle is a straight line segment whose endpoints both lie on the circle. The infinite line extension of a chord is a secant line, or just secant. ... A chord that passes through a circle's center point is the circle's diameter. The word chord is from the Latin chorda meaning bowstring.
3. Radii is half of diameter
4. ..
5. an abrupt change of course : digression the speaker went off on a tangent. 2a : the trigonometric function that for an acute angle is the ratio between the leg opposite to the angle when it is considered part of a right triangle and the leg adjacent.
6. In geometry, a secant of a curve is a line that intersects the curve at a minimum of two distinct points. The word secant comes from the Latin word secare, meaning to cut. In the case of a circle, a secant will intersect the circle at exactly two points.
7. Angle form at center
