For the last two weeks we have been learning about angles. We have learned a lot of things. We learned how to properly measure angles. Which is to align one ray on the zero and then you count the numbers until you get to the other ray. We learned that a vertex is the point in which the rays meet. We also learned the different types of angles which are the acute angle which is and angle that is smaller then 90 degrees, and obtuse angle is an angle that is greater than 90 degrees, a right angle is a 90 degree angle, a reflex angle is an angle that is greater the 180 degrees but is smaller than 360 degrees, a straight angle is an angle that is 180 degrees so its basically a straight line,
