## Geometry Files: More Triangles? Are you serious?

Posted on 0 comment

Yes, I’m totally serious.  (see more files and FAQs here)

But we already did triangles, you say. Sure, we looked at congruent triangles, but did we look at stuff that can happen inside triangles?!?!  There’s a lot of good discovery activities for these rules, also here are some rudimentary geogebra files I made:

(files: medians, perpendicular bisectors, angle bisectors) then we can solidify everything:

(file here) Oh, plus there’s this weird thing about medians:

I make mine draw out and label the median for each problem; the visual seemed to help a lot of them see the relationship between what was given and what we need.

Homework:

Then let’s put all this together!

(file here) “Boy, Meg, sure wish there was a powerpoint to go along with this!”  Why, it’s your lucky day!

Then another powerpoint for exterior/interior angle and angle/side inequalities:

Then I guess I did more stuff with possible sides of a triangle?  Then some practice:(file here) wiiiiiiiith powerpoint!

And more inequalities!!

ARE WE DONE WITH THESE TRIANGLES YET?!?!?!?!

Yes!  Now just a review!

(file here) and powerpoint:

Finally!  There can’t be anything else we can do with triangles, right?!?!  (Shh…we won’t talk about trig coming up, ok?)
