Question

In the given fig, ABııCD, EF is transveesal, then Write,
1) at the pair of alternative angles
2) the pair of allied angles and their characteristics
​

Answer 1

Answer:

1) at the pair of alternative angles

Answer 2

Solution :-

Pair of alternate interior angles in the image are :-

• (a , a') => ∠a = ∠a'
• (b, b') => ∠b = ∠b'
• They are pair of angles lies in the inner side of the two parallel lines but on the opposite side of the transversal.

Pair of alternate exterior angles in the image are :-

• (c , c') => ∠c = ∠c'
• (d, d') => ∠d = ∠d'
• They are pair of angles lies in the the outer side of the two parallel lines but on the opposite side of the transversal.

alternate angles are equal in measure .
