Messages to the Future
- Page is developed and ready to go. Steve said that proofs for each case should be provided. I left instructions to future editors at the bottom of the page saying this.
References and footnotes
- All images are properly attributed.
- No direct quotes.
- Since this page is about basic trigonometry, I was able to write it based on my knowledge of the subject. External sources were only consulted to remember the cases, not for content.
- The page goes case by case, and finishing one before moving on to the next.
- The cases appear in an intuitive order, with the cases that do not necessarily imply congruence explained after those that do.
- I suggest using the word "it" instead of "the former" in this sentence: Congruence is similar to equality, however, the former is used for shapes. CHECK
Integration of Images and Text
- Wherever an image or animation is used to help with an explanation, the reader is explicitly instructed to refer to the image.
- The text explicitly points out what the reader should observe in a picture.
- Each case has a corresponding image that illustrates the explanation.
- The Ambiguous Case is a link.
Connections to other mathematical topics
Examples, Calculations, Applications, Proofs
- New ideas, like congruence and similarity, are introduced with definitions.
- I've included a proof for the AAA case, and left instructions for the page telling future contributors to add proofs for the other cases.
- I think that the Solving Triangles page is the one to deal with the proofs for the other cases, because that is exactly what the proofs would be: solving a triangle given a certain scenario. Steve disagrees, and thinks that the proofs should be included on this page. This is why I've left the addition of these proofs to another person. In light of my opinion on the matter, the page is quite complete, and is designed to be coherent with or without these proofs.
Mathematical Accuracy and precision of language
- I believe the page to be quite clear and accurate.
- As previously stated, I gave definitions and explanations when introducing new/ key concepts.
- No further comment.
Htasoff 21:28, 30 May 2011 (UTC) Add part on the two cases where triangles cannot be determined to be congruent.
I found the highlighting scheme counter-intuitive when looking at the images. Oringinally I thought that sides were highlighted in red when used and angles were in green, but it looks like the sides are red when the angles are used? I'm not really sure what's going on.
--I went back and looked at it again and it looks like someone possibly flipped whether they were highlighting angles or sides by accident
--I looked at it for a third time and I think that the highlighting is being done in black and the red and green are un-highlighted. I think it would make much more sense the other way around if red and green meant highlighted sides and angles (July 6).
- Nordhr 17:53, 24 June 2011 (UTC) I understand, and can see how it is confusing. That is why I included an explanation of the colors right below the list of cases.
Okay, I see that now. Originally I was just scanning through the page and I missed that entirely. Maybe it would be helpful to put the color names in bold or something like that to make it more noticable? Just a thought.

- Rebecca 18:37, 11 June 2011 (UTC) In the first sentence, I would change congruence to congruence to be consistent with the notation for definition rest of the pages.CHECK
- "If their are different sets of congruent segments, the one set is marked with one line, the next, with two, and so on." should be "If THERE are different..." CHECK
- Rebecca 18:51, 11 June 2011 (UTC) This is a great section. I think it's nice how your briefly introduce each case, and then fully explain them later in the different sections.
- The equations below "We begin with the first two parts of the Law of Sines for our two triangles:" get thrown off a little on my computer screen. Is there a way to fix this? If not, it's not a really big deal.
- I think this sentence is a bit awkward... "Because sin θ2 occurs on both sides of the equation, dividing by it eliminates it, leaving..." and could be changed to "Because sin θ2 occurs on both sides of the equation, dividing by sin θ2 eliminates it, leaving".Not there any more.
