Answer 1

To verify that the opposite angles of a cyclic quadrilateral are supplementary by paper folding activity. A quadrilateral whose all four vertices lies on the circle is known as cyclic quadrilateral.

Answer 2

Answer:

: .

: ∠ + ∠ = 180° ∠ + ∠ = 180°.

: .

: ∠ = 2 ∠

∠ = 1/2∠

∠ = 1/2 ∠

∠ + ∠ = 1/2∠ + 1/2 ∠

=1/2(∠ + ∠)

= (1/2)360° = 180°

∠ + ∠ = 180°
