An angle is figure formed by two sides that meet in a point called a vertex An angle is measured in a unit of measurement called degrees
3
An acute angle is an angle that has a measurement lower than 90 degrees
4
An obtuse angle is an angle that is larger than 90 degrees but less than 180 degrees
5
A right angle is an angle that is exactly 90 degrees
6
A straight angle is an angle that is exactly 180 degrees

8
A protractor is a tool that is used for drawing and measuring angles.You can measure and draw them using little ticks called degrees
9
You measure an angle by putting the baseline on a ray of the angle. Then you place the midpoint on the vertex and look on where the other ray meets on the scale. Make sure to use the right scale
10
The first step is to draw a small dot that will be your vertex. Next you draw a line with your ruler or protractor through the vertex. After, you use the same steps as if you were measuring it and make a tick on the degree were you want your angle to be. The last step is to draw a line from your vertex to your little mark.
11
I feel I have really learned a lot. I think I am really good at drawing angles now. And I also think I'm good at identifying if they are acute, obtuse,straight or right
12
I found measuring angles really difficult because I had trouble lining the midpoint right on the vertex. In practice I think I will get the hang of it.
