Question

what is the meaning of an angel inscribed in semicircle ?​

Answer 1

Answer:

Every angle inscribed in a circle is one half an angle with its apex at the center, if they both share the same arc. An angle inscribed in a semicircle shares the semicircle with a diameter, which is a 'straight angle'. Half of a straight angle is a right angle.In geometry, an inscribed angle is the angle formed in the interior of a circle when two secant lines (or, in a degenerate case, when one secant line and one tangent line of that circle) intersect on the circle. It can also be defined as the angle subtended at a point on the circle by two given points on the circle.An inscribed angle in a circle is formed by two chords that have a common end point on the circle. This common end point is the vertex of the angle. Here, the circle with center O has the inscribed angle ∠ABC. The other end points than the vertex, A and C define the intercepted arc ⌢AC of the circle.
