Answer:
circles: A circle is a plane figure bounded by one curved line, and such that all straight lines drawn from a certain point within it to the bounding line, are equal. The bounding line is called its circumference and the point, its centre.
centre of circles:The center of a circle is the point inside a circle that is the same distance from each point on the circle.
circumference: the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment.
diameter:a straight line that goes from one side to the other of a circle, passing through the centre
radius:a straight line extending from the center of a circle or sphere to the circumference or surface: The radius of a circle is half the diameter. the length of such a line.
chord:a straight line that joins two points on a curve
segment:Segment (of a Circle) A segment is a region bounded by a chord of a circle and the intercepted arc of the circle. A segment with an intercepted arc less than a semicircle is called a minor segment.
tangent:The tangent to a circle is defined as a straight line which touches the circle at a single point. The point where the tangent touches a circle is known as the point of tangency or the point of contact.
point ofcontact: Point of contact refers to the location where two different lines or curves or angles meet. In case of Tangents, the point on circle at which tangent is drawn to a circle, is known as point of tangency.
arc:a curved line, part of a circle
angle of major arc: Major Arc. A major arc is an arc larger than a semicircle. A central angle which is subtended by a major arc has a measure greater than 180°.
angle of centre: A central angle is an angle whose apex (vertex) is the center O of a circle and whose legs (sides) are radii intersecting the circle in two distinct points A and B. ... The central angle is also known as the arc's angular distance. The size of a central angle Θ is 0° < Θ < 360° or 0 < Θ < 2π (radians).
angle at circumference on minor arc:Minor arcs are associated with less than half of a rotation, so minor arcs are associated with angles less than 180°. Major arcs are associated with more than half of a rotation, so major arcs are associated with angles greated than 180°.
sector:There are two main "slices" of a circle: The "pizza" slice is called a Sector. And the Segment, which is cut from the circle by a "chord" (a line between two points on the circle).
congurent circles:All circles of the same size are congruent to one another. "Size" can refer to radius, diameter, circumference, area, etc.
semi circle:In mathematics, a semicircle is a one-dimensional locus of points that forms half of a circle. The full arc of a semicircle always measures 180°. It has only one line of symmetry.
perpendicular:Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect. Perpendicular lines are lines that intersect at a right (90 degrees) angle.
bisectors :The line that divides something into two equal parts.
You can bisect line segments, angles, and more.
non- collinear: The points which do not lie on the same line are called non-collinear points.
equidistance:equally far from two or more places
concentric circles: Two or more circles which have the same center point.
The region between two concentric circles is called an annulus.
subtended:A subtended central angle is the angle formed at the centre of the circle and the legs of the angle are the radii of the circle intersecting the circle at two different points.
