Step-by-step explanation:
Let say ABCD is a Quadrilateral Circumscribing a Circle
AB touching at P
BC touching at Q
CD touching at R
AD touching at S
AP = AS ( Equal tangent)
BP = BQ
CQ = CR
DR = DS
AB + CD = AP + BP + CR + DR
= AS + BQ + CQ + DS
= AS + DS + BQ + CQ
= AD + BC
AB + CD = AD + BC
sum of opposite sides are equal
