Arcs and Chords

Thursday, May 19, 2016
Here are the INB pages for arcs and chords in circles. We went over past vocabulary terms on the following Theorems page, highlighted key words, and filled in the blanks. This is a new page that I made and I am so glad I did because I love when I see a page filled with important geometry terms.

After we filled out the theorem sheet, we filled out the foldable. I would say that the second theorem ("In a circle, if a diameter (or radius) is perpendicular to a chord, then it bisects the chord and its arc") was the most difficult of the three. I made 2 typos that I forgot to fix last year that are shown in the pictures below, but it's fixed now. Also, I did add "find DE" to question 3 because that questions always seems to throw some students off when I ask them. 

Students worked on their arcs and chords HW and had the most questions on #6. Maybe edit question 4 on the foldable to reflect that question for next year?


You can find the files that I used in this lesson when you click here:


  1. Is there a back to the homework? Thanks!

  2. I like your HW pages! I don't see a link to the file. :( Would you mind sharing it?

  3. I saw your comment that most students had questions on HW #6. I only see #1-4. Is there a second page I am not seeing? Thank you!
