Mathematical Reflections on Polygons

1. The common properties of polygons are... 
Polygons are multisided, meaning that they have more than one side. The sides must be straight and there can be no curves. Polygons also are closed, meaning that there are no gaps on the edges. There cannot be intersections, which means that there can't be anything inside the polygon. Also, the number of lines should be equal to the number of vertices. Finally, polygons are 2D/planar and the vertices must be on the same plane as the shape.



2. The measure in degrees in an angle tells me that the angle... Some of the common angles are... 
Some common angles are 90°, 180° , 270°, 360°.

3. Some strategies to estimate angle measures are... To find accurate measurements with tools, I should...
A strategy is to look at benchmark angles like 45° and 90° and see how close the angle is to the benchmark angle. Then you can change the angle by 5 or 10 to get a good estimation. To find accurate measurements, you should use a protractor. A protractor measures angles.

1. What is the difference between an Observations and an Inference?

An observation is something that you observe, like things that you smell, see, hear, taste, and touch. An inference is an educated guess like a conclusion which you can find with your observations.

2. How can inferences and observations be related?

They both can help you find out the answers to questions. They are both pieces of information. 

3. Why are both observations and inferences important in science?

They can help you determine questions or things that aren't clear.
