Puzzle Sheet

I'm proud of this puzzle sheet I just made, and I like the self correcting aspect of these things. I think that if I had 20 more hours each day, I could spend my time making these types of things up. Notice that it basically has the exact same pictures from the previous sheet, but now the students have to place the vertices in order and determine what type of triangle congruence it is.

After we had our day of constructing triangles in geometry to see if they were all congruent or not, and after we discussed how to read information, then I had the kids learn about the various postulates and theorems (SAS, SSS, ...). THEN they're ready for this puzzle just to see if they can piece things together. If they complete the congruence statement with the triangle vertices in the right order, and if they correctly place them on the blanks at the bottom, then an interesting fact appears. (UPDATE: yeesh! There was a typo on the picture in #10, but it's fixed now in the download.)

1. I'm tired just thinking about the effort this took to make. Is geometry your only prep?

2. Well, it was a BUNCH of copy/paste actions, so that saved time. Also, depending on how you count it, I have either 2 or 2.5 or 3 preps: engineering, and geometry for 2 different levels of kids. So, yes, I have a lighter load this year. From what I hear, either I'll have 3 or 4 (5?) preps next year ... no more worksheet creating for me.

what letters r u supposed to put in the blanks

2. That was one enjoyable geometry worksheet, BTW you kinda resemble a snake. Fun fact - I am a snake. I shed my skin until I die.................... Do you stalk me? How do you know I shed my skin? You are CRAZY MS.COOKIE, CRAZY I TELL YA!!!!

3. I was unable to resolve the puzzle! you seem to be a math GURU! Simply superb blog to be bookmarked..keep it up

5. Thank you for creating this! It's a fun puzzle!

6. Thank you!! Will use this as a review and extension when we get to congruent triangles. Thanks, again!

7. Thank you!! Will use this as a review and extension when we get to congruent triangles. Thanks, again!

8. I am trying to download this, but it isn't allowing me. I would really like to borrow it if possible. Thanks! :)

9. Is this honestly what you do with your life? Ms....Cookie? I need an explanation for that name because who just thinks. Hmm. I bet Ms. Cookie would be a cool name. HMMM!!! LET'S DO THAT!!!! WOOPDY FREAKING DOOO!!! OH BOY!!!

10. Feels like I'm always nagging at my kids to write their congruence statements in the right order; like no, you can't just write the letters down in any order and try to convince me that you're right because 'it's still congruent'. I love how there's a secret message that they're looking for to keep them engaged until the very end! Definitely more exciting than some of those repetitive worksheets I've seen.

1. Thanks! Hope it's useful.

11. give me the answer key

1. A reason snakes shed is that they keep growing until they die

12. is there an answer key so I can check my answers
