2.  An angles are two sides that touch each other at an vertex.  Angles are measured in degrees. http://www.youtube.com/watch?v=gshd5Hj CQzs&safety_mode=true&persist_safety_mod e=1&safe=active http://www.youtube.com/watch?v=gshd5Hj CQzs&safety_mode=true&persist_safety_mod e=1&safe=active

3.  An Acute angle is a angle that is more than 0 degrees and less than 90 degrees.

4.  A right is 90 degrees.

5.  An obtuse angle is an angle that is more than 90 degrees and less than 180 degrees.

6.  A straight angle is 180 degrees or a straight line.

7.  First you look if it is a right, acute,obtuse, or straight angle  Then you can fold a paper on one side 45 degrees the other side 90 degrees and the other side 135 degrees.  http://www.youtube.com/watch?v=YRFhA2h HCBM&safety_mode=true&persist_safety_mo de=1&safe=active http://www.youtube.com/watch?v=YRFhA2h HCBM&safety_mode=true&persist_safety_mo de=1&safe=active

8.  A protractor is a tool to measure angles.  A protractor can be in two shapes a half circle or a circle.  A protractor is to measure angles and a ruler is to measure lines  A protractor has a midpoint, an inner scale, an outer scale, and the degree on the side. outer scale inner scale degrees midpoint

9.  To measure an angle you use a protractor.  You use the midpoint and put it on the vertex Than you rake the baseline and straight it up with one of the line. There is one thing that you can mess up on it is a wrong scale. The wrong scale is when you use the bigger number when it is a acute.http://www.youtube.com/watch?v=Fec lDm7pVcI&safety_mode=true&persist_safety_ mode=1&safe=activehttp://www.youtube.com/watch?v=Fec lDm7pVcI&safety_mode=true&persist_safety_ mode=1&safe=active

10.  You put one dot where you want the vertex to be.  Then you make another dot on the other side and make a line from one dot to the other dot. Than you make a another dot where the degree you want to be.  http://www.youtube.com/watch?v=P4- 3oXmgBsM&safety_mode=true&persist_safety _mode=1&safe=active http://www.youtube.com/watch?v=P4- 3oXmgBsM&safety_mode=true&persist_safety _mode=1&safe=active

11.  I thing that I did well on is on measuring with an protractor

12.  My challenge for next step is to draw the angles better.
