  2. Good job. You explained everything well. I like how you put more than one video. There was one small problems I saw. It was that 2 of the colors in the circle graphs looked the same. Other than that you did good.

  6. Good job Ivan. Your post was easy to understand. I liked the colours you used when you were writing the answers and your pictures were clear with good colour too. Thanks for putting the links. You did a great job except for one mistake in the beginning when you wrote 'connecting by 2 radii' it should have been 'connected by 2 radii' to make better sense, but overall great post!(:

  13. Good job Ivan Salvador:) You're pictures were colourful. I liked them. When you guys did that in class, I wasn't there. I couldn't really understand how to find the answer to the questions. Maybe next time you can put how to find the answer because I was really confused.

  18. Nice job Ivan(: I like how you explained what everything was and that you included the textbook website in your post(: One thing you should improve on is making the picture accurate to what we learned in class because I believe that the angle bisector is a right angle. Other than that, good job(:
