Answer:
1) Center = A → centermost point of a circle.
2) Radius = AB, AC → distance from centre to any point on the surface of the circle.
3) Diameter = BC → longest chord; distance from 1 point of the circle to another which passes through the centre of the circle.
4) Chord = IH → distance from 1 point on the circle to another.
5) Tangent = GF → external line which passes through only 1 point of the circle.
6) Secant = DE → external line which passes through 2 points on the circle.
