Lately we have been learning about measurements in math and it has actually been exciting! That almost NEVER happens. I have learned the vortex of an angle, some angle names, and also how to use a protractor. The vortex of an angle is where the two lines that form an angle meet. I can give the names of the angles that we have learned and they are acute, obtuse, reflex, straight, and right. And, to end my reflection I am going to tell you how to use a protractor, a protractor is actually fairly easy to use and you line up the very center of the protractor with the closest line where all the lines meet as i said earlier the vortex and you MUST start at the zero and then you count up to the other line and remember to keep the numbers right if it is acute should the number be 124 degrees?
