Q1 of 12 Page 109

In the figure, seg SD and seg TN are diameters. Name those minor arcs, major arcs and semicircular arcs whose endpoints are also the endpoints of these diameters.

According to the diagram


⇒ Taking point S & T of diameters


Minor arc = SXT


Major arc = SMT


⇒ Taking point S & N of diameters


Minor arc = SYT


Major arc = SZN


⇒ Taking point N & D of diameters


Minor arc = NMD


Major arc = NXD


⇒ Taking point D & T of diameters


Minor arc = TZD


Major arc = TYD


As we know that:-


SD & TN are diameters of circle


⇒ Taking diameter SD


Semicircular arc are STD & SND


⇒ Taking diameter TN


Semicircular arc are TSN & TDN

In the figure alongside, name the angles which intercept the arc LXT.

 2

Observe the figure and name the angles which intercept arcs and name the arc that each angle intercepts.

 1

If the measure of a central angle is 120°, find the measure of the corresponding minor arc and that of the major arc corresponding to this minor arc.

 2

The measure of the minor arc of a circle is 160°. Hence, find the measures of the corresponding central angle and the corresponding major arc.
