Hi, in this question, this is the given figure.
00:05
Here we have to determine whether m and n are parallel lines.
00:09
We have to justify the answer.
00:11
Here we have to consider a, b, c, d, p, e and here this is the straight line.
00:25
We know that the straight line angle is that is here we have to consider o.
00:32
So angles o, b, o, c equals 180 degree.
00:46
So here we can write it as angle ao, b equals 130 degree.
00:55
So we can write it as angle aoc equals 180 degree minus 130 degree which is equal to 50 degree.
01:10
So here we can write it as this as 50 degree.
01:15
Therefore, angle aoc equals angle op, e...
