The converse of the side-splitter theorem states that if a line intersecting two sides of a triangle divides the two sides proportionally, then it is parallel to the third side. A triangle midsegment creates a smaller similar triangle nested inside the larger triangle. Midsegment LJ. LJ. 12. The first step is always to find the scale factor: the number you multiply the length of one side by to get the length of the corresponding side in the other triangle (assuming of course that the triangles are congruent). In this case you have to find the scale factor from 12 to 30 (what you have to multiply 12 by to get to 30), so that you can ...There are 5 ways to prove congruent triangles. SSS, SAS, AAS, ASA, and HL for right triangles. To prove similar triangles, you can use SAS, SSS, and AA.2. The sides of an equilateral triangle are 8 units long.

If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion. Picture three angles of a triangle floating around.Using Triangle Congruence Theorems Proving Base Angles of Isosceles Triangles Are Congruent Given: ABC is isosceles with AB BC≅ .
