What Is The Measure Of Angle Acb - Web 108 ∘ + ∠ b a c = 180 ∘ ∠ b a c = 180 ∘ − 108 ∘ ∠ b a c = 72 ∘. Ibe i b e is a special right triangle with perp sides in ratio 1: We can use a protractor to measure how many degrees an angle is. Web hence, ∠cam = ∠cmi = 2∠cbi =16∘ ∠ c a m = ∠ c m i = 2 ∠ c b i = 16 ∘. Angles are measured in degrees. Web in order to figure out if an angle is congruent or not, use your congruent angle postulates: Therefore, ∠acb =180∘ − ∠a − ∠b = 180∘. Similarly, we know that a b f is a straight line so, ∠ a b c + ∠ c b f =. Web from (1) ( 1) and (2) ( 2), be = 2bi b e = 2 b i.
