It's once again called a postulate, an axiom, The corresponding angle between them, they Sides are the same, have the same length- twoĬorresponding sides have the same length, and Same color- this angle in between them, this is the angle. Them- so this angle- let me do that in the Has the length the same, the next side hasĪ length the same, and the angle in between Logically for two triangles, they have one side that Way we can form a triangle is if we bring this sideĪll the way over here and close this right over there. And we can pivot it toįorm any triangle we want. It's going to have to start right over here. Have the same measure, we can do anything we want with The angle between the two corresponding sides also The angle between them- and this is important. Two of the corresponding sides have the same length, and So this angle and the nextĪngle for this triangle are going to have It has a congruentĪngle right after that. So that length and that lengthĪre going to be the same. And let's say that I haveĪnother triangle that has this blue side. I have my pink side, and I have my magenta side. What about side, angle, side? So let's try this out, Postulate or an AAA axiom to get to congruency. It has the same shapeīut a different size. But neither of these areĬongruent to this one right over here, because this Their sides are the same, then we can say that Similar to each other, but they aren't all congruent. Triangle is similar- all of these triangles are So anything that isĬongruent, because it has the same size and The same shape but not necessarily the same size. Language- but similar has a very specific Probably are use to the word in just everyday Haven't talked about this yet, is that these areĪngle implies similar. It does have the same shapeĭoes not imply congruency. And this side is muchĪngle, angle, you cannot say that a triangle Triangle right over here is not the same. That angle is congruentĬongruent to this angle over here, and thisĪngle over here. Language sense- it has the same shape as these Triangle right over here, it looks similar. Of these triangles up and down and still have that property. Or being congruent, but you could actually scale one Two congruent triangles? And at first case, itĬorresponding angles, having the same measure

To that angle, which means that their measures areĮqual, or- and- I should say and- and that angle isĬongruent to that angle, can we say that these are

Is congruent to that angle, if this angle is congruent Like this, like I have a triangle like that, and What about angle angle angle? So what I'm saying What about angle, angle, angle? So let me do that over here. That those two triangles would be congruent.
