Question

a quadrilateral SEO and you are bisectors of angle C and angle D respectively prove that angle A + Angle B = 2 angle COD​

Answer 1

Answer:

Step-by-step explanation:

in TRIANGLE COD

angle COD + OCD +CDO= 180 deg (angle sum property)

angle (OCD AND COD) WILL BE 1 AND 2

angle COD =180-(1 +2)

COD=180- 1/2(1+2)

        =180-1/2[360 deg - angle (A +B)

       =180 -180 +1/2 angle (A+B)

COD = 1/2 angle (A+B)
