Hi ToucanComique7953,
Thank you for your question!
Usually, you'll need a relation to justify the angles in a figure. For example, the sum of the interior angles of a triangle is equal to 180°, a straight angle is 180°, a right angle is 90°, etc.
There are a lot of relations that exist in mathematics to justify the measures of angles. I gave you a few, but you'll learn a lot more. Here's a link to help you!
I hope that helps and feel free to write us again!

See if there's a place in your textbook containing the justifications. If not, you should ask your teacher.
