  • question_answer 18) Draw a rough sketch of a quadrilateral KLMN. State, (a) two pairs of opposite sides. (b) two pairs of opposite angles. (c) two pairs of adjacent sides. (d) two pairs of adjacent angles.

    Answer:

    A rough sketch of a quadrilateral KLMN is given here Now, from the figure (a) KL, MN and LM, NK are two pairs of opposite sides. (b) \[\angle K,\angle M\]and \[\angle L,\angle N\]are two pairs of opposite angles. (c) KL, LM and LM, MN are two pairs of adjacent sides because end point of one line is starting point of another line. (d) Two angles are called adjacent angles, if they have common vertex. Hence, \[\angle K,\angle L\]and \[\angle L,\angle M\]are two pairs of adjacent angles because they have the common vertex L.
