We spoke earlier about the 3-4-5 triangle being a right triangle. Of course, not all 3-4-5 triangles are going to be congruent because someone might use 3 attometers, 3 miles, or even 3 light-years. However, because of the Pythagorean Theorem these are all right triangles.

State the postulate or theorem you would use to prove each pair of triangles congruent. If the triangles can not be proved congruent, write not possible. 1. We also learnt that the sum of the angles in a triangle is 180°. If two triangles have the same size and shape they are called congruent triangles. If we flip, turn or rotate one of two congruent triangles they are still congruent. If the sides of two triangles are the same then the triangles must have the same angles and therefore must be ...

Proving Triangles Congruent We just started talking about congruent triangles in geometry. After a day of notation and vocabulary and such, I start up the class with asking them how many pieces of information a triangle has (6). If I have a triangle that looks something-- I have trouble drawing straight triangles. So let's say the triangle looks something like that. And let's say that we've found another triangle that has a congruent side, a side that is congruent to this side right over here. I guess any side on a triangle is next to the other two sides.
