question 4: standard g.c.2
this diagram shows which part of a circle?
diagram of a circle with points a (center), c (on the circle), b (on the circle)
a. radius
b. chord
c. diameter
d. arc

Explanation:

Question 1

A chord is defined as a line segment with both endpoints on the circle. Option a matches this definition. Option b is incorrect (a chord can go through the center, like a diameter). Option c describes a radius. Option d describes a tangent.

A diameter is a special chord that passes through the center of the circle. Option a fits this. Option b is incorrect (diameter goes through the center). Option c is a radius. Option d is a tangent.

A radius is a line segment from the center of the circle to its edge. Option c matches this. Option a is a diameter (if it's a segment) or a line through center (not radius). Option b is a non - diameter chord. Option d is a tangent.

Answer:

a. A line segment whose endpoints lie on a circle
