| 1. This is a polygon |
The common properties of polygons are they have to be closed, they can't intersect and they can't have any curves. Also 3D shaped can't be polygons because they have intersections.
2. The measure of degrees in an angle tells me that the angle is ...
The measure of angle tells me that it is either acute obtuse or right. Any angle that is less then 90˚ acute any angle that is more than 90˚ is obtuse and 90˚ is right
3. Some of the common angles are...
Some of the common angles are right angles (90˚) obtuse angles (>90˚) and acute angles (90˚>)
4. Some strategies to estimate angle measures are... Some strategies to estimate the angles are I think of a major angle close to it. Like the angle could be 85˚, but I would round it to 90˚. The main angles are 45˚ 90˚ 180˚ 360˚ etc.

To find accurate measurement with a protractor I should line up the the dot on the line and when I'm measuring I need to draw the line straight to make sure i get the correct measurement. When I am done measuring the angle I will need to double check to make sure everything was lined up correctly.

| 3. The one on the left is a right angle, the one in the middle is obtuse and the one on the right is an acute angle |
