One sector in the diagram is:
iklv
ytxk
ulyk
xkiy

The sector of the given circle is IKLV

Step-by-step explanation:

Given as :

The figure shown is the circle

The circle have chord as UT and VT

Both chords UT and VT meets at points T outsides the circle , and intersect the circle at Y and I

Now,

Points L and I are on the circle with center K

The line is drawn joining center K and point L as KL which is the radius

The line is drawn joining center K and point I as KI which is the radius

Now, A sector is the area enclosed by two radius and arc

So, here KL and KI are two radius and LI is the arc

So, IKLV is the sector

Hence the sector of the given circle is IKLV  . Answer
