alright hello everybody my dear geometry students these are your video notes for Section 4.7 or talking about overlapping triangles overlapping triangles please make sure that you copy your title and you update your table of contents these notes of course are part of quarter 2 here we go first theorem theorem 4.5 no name to this one we're going to be talking triangles so let's get started if a line bisects the vertex of an isosceles triangle okay so if it by 6 or texting you have two congruent triangles what is that mean then that line is a perpendicular bisector of the base what does that look like this is what we're talking about so notice of there's a few things happening you have a a triangle which means that the sides are congruent doesn't mean that the angles are congruent so be very careful I saucily's triangle means that the sides if this vertex right here is being split with a line bisector that means that you have an angle here and then go there that are congruent but it also now as means that you have a perpendicular bisector or 90 degree which gives you a right triangle in the right and on the left so there's a lot of things happening with this theorem mixed up corollary what's a theorem that can be proved so now we have theorems postulates definitions corollaries and it'll be more these are all mathematical it's basically last one one more I am to study or property corollary 4.3 be aware that this corollary does have a converse with biconditional it's Converse in your textbook is called corollary 4.4 and if that's important what's important is that you understand that this concept is it by conditional here we go if a triangle is equal or equilateral means that all sides are the same then that triangle is equiangular equiangular meaning that all three angles are the same if it's a biconditional right then that means if you have a triangle with all three angles equal to each other or congruent then that means that all three sides have to be also congruent so I can go both ways that is it
