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:

(file here)

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

(file here)

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?)
