Question

1. Prove that sum of the measure of the external angles of any

polygon is 360 0 i;e m<1+ m <2 + m <3 + m <4 + m <5= 3600​

Answer 1

Answer:

Given: parllelogram ABCD circumscribe a circle.

To prove: we know that pain syndrome from the extent part are equal in length.

AP=AS-------1

BP=BQ-------2

CR=CQ-------3

DR=DS-------4

Adding 1,2,3 and 4

AP+BP+CR+DR=AS+BQ+CQ+DS

AB+CD=AD+BC-------5

ABCD is a parllelogram

AB=CD

----------6

AD=BC

From 3 and 6 we get

AB+AB=AD+AD

2AB=2AD

AB=AD

If adjacent sides of parllelogram are equal then it becomes rhombus.

Hence ABCD is a Rhombus.
