Question

20 Define i) Minor sector ii) Minor segment iii) semicircle with figures ​

Answer 1

Answer:

i) Minor sector=A sector with a central angle less than 180° is called a minor sector.

ii) Minor segment=A segment with an intercepted arc less than a semicircle.

iii) semicircle =a semicircle is a one-dimensional locus of points that forms half of a circle. The full arc of a semicircle always measures 180°. It has only one line of symmetry.

Answer 2

_____________Anwser_____________

Minor sector - A sector is a region bounded by two radii of a circle and the intercepted arc of the circle. ... A sector with a central angle less than 180° is called a minor sector. A sector with a central angle greater than 180° is called a major sector.

Minor segment - A segment is a region bounded by a chord of a circle and the intercepted arc of the circle. A segment with an intercepted arc less than a semicircle is called a minor segment.

Semicircle - A is a one-dimensional locus of points that forms half of a circle. The full arc of a semicircle always measures 180° (equivalently, π radians, or a half-turn). It has only one line of symmetry (reflection symmetry).
