 Welcome to problem solving session on lines and angles guys. So in this question It's given that m is parallel to n and angle 1 is given to be equal to 65 degrees So this is 65 degrees. You have to find angle 6 and angle 7. Okay, so Let's start. So what is it if you see angle 1 you have to find out angle 6 and 7, right? So hence 7 is equal to 5, you know, right vertically opposite angle. So hence we say angle 1 is equal to angle 5 and these are corresponding angles corresponding angles Corresponding angles that means angle 5 is also equal to 65 degrees Because angle 1 was 65 degrees Now angle 5 is equal to angle 7 is equal to 65 degrees. Why is this? They are vertically Opposite angles Okay, and then Angle 6 plus angle 7 is 180 degrees. Why? Because these are forming a linear pair That means Angle 6 is 180 degrees minus angle 7 Which is equal to 180 degrees minus 65 degrees, which is equal to 1 1 5 Degrees. Okay. So these kind of questions are easy guys So what you need to do is keep these things in your mind these things which we learned what all so first of all Angles related to a transversal these will be important. So you must know corresponding angles Corresponding Angles are equal then alternate Interior angles are equal then alternate exterior angles are also equal then adjacent angle adjacent angles are Supplementary Supplementary is you must know right What else then you must know linear pair and Vertically opposite angles Right, they are equal. So all this if you know this you will be able to solve such problems So hence it was pretty simple problem in this case. Let's take up some more
