Three
Six
Four
Two
Every quadrilateral has four pairs of adjacent angles.
Example: For the quadrilateral ABCD, the pairs of adjacent angles are (i) ∠A, ∠B (ii) ∠B, ∠C (iii) ∠C, ∠D (iv) ∠D, ∠A
In the figure, ABCD is a quadrilateral. (i) Name a pair of adjacent sides. (ii) Name a pair of opposite sides. (iii) How many pairs of adjacent sides are there? (iv) How many pairs of opposite sides are there?
(v)Name a pair of adjacent angles. (vi) Name a pair of opposite angles. (vii) How many pairs of adjacent angles are there? (viii) How many pairs of opposite angles are there?
