Write True or False: Give reasons for your Solutions.
(i) Line segment joining the centre to any point on the circle is a radius of the circle.
(ii) A circle has only finite number of equal chords.
(iii) If a circle is divided into three equal arcs, each is a major arc.
(iv) A chord of a circle, which is twice as long as its radius, is a diameter of the circle.
(v) Sector is the region between the chord and its corresponding arc.
(vi) A circle is a plane figure.
(i) True
Line segment joining the centre to any point on the circle is a radius of the circle and equidistant from the centre
(ii) False
An infinite number of equal chords in circle
(iii) False
Equal arcs on a circle can't be a major arc or a minor arc
(iv) True
Diameter = 2 x Radius
(v) False
Region of a circle between the arc and the two radii of the circle is sector.
(vi) True
A circle is a plane figure
