Examples for Practice

1). Draw a rough sketch of quadrilateral PQRS. Draw its diagonals. Name them. Is the meeting point of the diagonals in the interior or exterior of the quadrilateral?

     The meeting point of the diagonals is in the interior of the quadrilateral.

2). Draw a rough sketch of quadrilateral KLMN. State,

     

a). two pairs of opposite sides.

     KL and MN or KN and ML are the pairs of opposite sides.

b). two pairs of opposite angles.

      ∟K and ∟M or ∟N and ∟L are the pairs of opposite angles.

c). two pairs of adjacent sides

     KN-KL, NM-NK, MN-ML, LM-LK are the pairs of adjacent sides.

d). two pairs of adjacent angles.

     ∟K -∟L and ∟K -∟N or ∟L -∟K and ∟L -∟M, ∟M -∟L, and ∟M -∟N, ∟N -∟M and ∟N -∟K are the pairs of adjacent angles.
