Webhe's taking from the first example- if one of the chords of the angle is the diameter then we already know that psi= 1/2theta, we already proved that. so using that we know that psi2=½ (theta2) and we can and since the huge angle we made also has one of the chords on the diameter, we can state that psi1+psi2=½ (theta1+theta2).

WebA central angle is an angle formed by two radii with the vertex at the center of the circle. The angle measure of the central angle is congruent to the measure of the intercepted arc. Central angle = Intercepted arc m∠AOB= m (AB) ̂ (In the above diagram) Let R be the radius of the arc which forms part of the perimeter of the segment, θ the central angle subtending the arc in radians, c the chord length, s the arc length, h the sagitta (height) of the segment, d the apothem of the segment, and a the area of the segment. Usually, chord length and height are given or measured, and sometimes the arc length as part of the perimeter, and the unknowns are area and sometimes arc length. These can't be calculate…
