WebApr 4, 2024 · Since ∠ E A B divide into ∠ E A D, ∠ D A C, ∠ C A B and A B C D E is regular pentagon so ∠ E A D = ∠ D A C = ∠ C A B. We know in the regular pentagon have interior angle ∠ E A B = 108 ∘, so we have ∠ D A C = 108 ∘ / 3 = 36 ∘.

geometry - Calculate the angle in the regular pentagon

WebTriangle ABE is isosceles, its base angles have sum 180 -108 = 72 Each base angle is half that, so angle ABE has measure 36 . Angle AED is an interior angle of the regular pentagon, so it has measure 108 . Angle AEB is the other base angle of the isosceles triangle ABE, so it is 36 . Angle BED = Angle AED - Angle AEB = 108 -36 = 72 Edwin WebIn a regular pentagon ABCDE, draw a diagonal BE and then find the measure of ∠BED. ABCDE is a regular pentagon with sides of length 6 cm.
