Hi there,

I just wanted to point out that the value of each vertical angle should always be less than 180 degrees (which is not always the case in these exercises), or else the angle becomes a line/ a reflex angle and therefore you can no longer call them a pair of vertical angles. Other than that, I think your mathematics exercises are great!
