Maths this week

This week in our maths class we have been learning about measurements and angles. The angles we have been learning about this week was acute, obtuse, right, reflex and straight. First of we use this game to see how good we can accurately measure these angles. Once we have got the hang of this game, we have to try measure angles that were given to us by our teacher. An acute angle is an angle that is less then 90 degrees. A right angle is exactly 90 degrees. The obtuse angle is greater then 90 but is less then 180 degrees. The straight angle is exactly 180 degrees and the reflex angle is greater then 180 degrees.

(below are some angles that we have measured in class)
can you figure out what the measurements of these angles are?
