Answer:
Explanation:
Vertical Angles are the angles opposite each other when two lines cross. "Vertical" in this case means they share the same Vertex (corner point), not the usual meaning of up-down
So we can see that we have 4 pairs of vertical angles in this figure
the pairs of vertical angles are:
(1 , 4) , (2 , 3) , (5 , 8) , (6 , 7)
use any one in your answer, they are all correct
A linear pair is a pair of angles on the same straight line and hence add up to 180 degrees
here, we have several pairs of linear pairs
(1, 2) , (3,4) , (5,6) , (7,8) , (1,3) , (2,4) , (5,7) , (6,8)
use any one of the above pairs, all these are correct answers
When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles
here, we have 2 transversals, 'l and m'
Hence we have 4 pairs of corresponding angles
Since congruent angles are just angles with the same magnitude, the corresponding angles are also congruent angles
(1,5) , (2,6) , (3, 7) , (4,8)
All the above are correct answers, you can use either one of them
