ScribeBadge11Okay so i didn't get to do my post when i was scribe last time cause my net wasn't being very nice. Today in class we did investigations 3 and 4.

Investigation 3:
1.(a) Use what you know about chords to find the centre of the circle. Erase all construction lines once you're done.

This is how you do question 1.(a) (If you do have any questions, this question is explained in the previous scribe):


(b)Construct diameter AB.

Heres what you do:



(c)Choose 4 different points on the circumference of the circle. Do not space them out evenly. Label these points C, D, E and F.

This questions is self-explanatory:



(d)Construct chords AC and BC.
(e)Measure the angle formed at C

Draw lines from A to C and from B to C and measure the angle C:


(f) Repeat steps (c) and (d) for the points labeled D, E and F.

It's pretty straight forward:



(g) What do you notice about all these angles? Can you articulate a general rule for what you have found? Your sentence should begin:
"If an inscribed angle is subtended by a diameter then...."
If an inscribed angle is subtended by a diameter then.... the inscribed angle is always 90°.

So that was Investigation 3. We started Investigation 4 but did not get a chance to go over it in class. THE SCRIBE FOR THE WEEKEND IS .. SANDY !

    I've been trying to stay out of the voting process and let the community around this blog work things out for themselves re: Hall of Fame nominations ... but Crysta! This is fantastic! Every time I think you've all perfected the art of sharing your learning you kick it up another notch!

    With a student away sick you have made it possible for him to experience, from a distance, exactly what and how we learned in class by using Bubbleshare to share your learning.

    Your post of worthy of entry into the Hall of Fame ... with distinction!
