C-08-Q098mediumsingle_mcq

The proof uses the fact that an exterior angle of a triangle equals—

athe third angle
bone interior opposite angle
cthe sum of the two interior opposite angles
dhalf the third angle

ব্যাখ্যা

The proof relies on the theorem that an exterior angle of a triangle equals the sum of the two interior opposite angles. Applying this to each isosceles triangle gives the central angle as twice the inscribed angle.
