![]() ![]() Quiz 2 - To write the congruence statement, match the corresponding vertices. ![]() That means that all pairs of sides are the same length and all pairs of angles have the same measure. A pair of congruent triangles have exactly the same size and shape. Side angle side means if you have a side and an included angle, which means if I said side de and side df the included angle would be angle d so it's the angle that's formed by those two sides then here you can also say those two triangles must be congruent. Quiz 1 - Using either SSS or SAS determine which triangles are congruent. In this lesson we’ll look at how to use triangle congruence theorems to prove that triangles, or parts of triangles, are congruent to one another. The second shortcut that we're going to talk about is side angle side. ![]() But what do side side side mean? It means if all you know is the 3 sides of one triangle are congruent and corresponding to the 3 sides of another triangle, then yes those two triangles must be congruent. There are a couple of shortcuts and we're going to talk about two. Do we always need to know that those 3 angles and those three sides are congruent? And the answer is no. So this is a whole work going on here there's 6 different parts of these two triangles that could be congruent. And then we can talk about the sides, de will be congruent to ab, bc would be congruent to ef and df would be congruent to ac. If two triangles are congruent, if I say that triangle abc and triangle def are congruent then that means that all of their corresponding parts are also congruent which means a and d will be congruent angle b and angle e will be congruent, angle c and angle f will be congruent. ![]()
