## TRIANGLE PARITY VE SIMILARITY

**Similarity Axioms**

1. A.A.A (Angle-Angle-Angle) Similarity:

If the two reciprocal angles of the two triangles are given equal, these two triangles are similar since the third angles of the triangle will be equal.

2. K.A.K (Side-Angle-Edge) Similarity:

If the two opposite sides of the two triangles are proportional and the angles between these sides are equal, these two triangles are similar.

3. K.K.K (Edge-Edge-Edge) Similarity:

If all the sides of the two triangles are in a certain proportion, the triangle is similar, or triangles whose opposite sides are proportional are similar.

4. K.K.A (Side-Edge-Angle) Similarity:

If the two sides of the two triangles are proportional and the angles opposite the larger ones are equal, these two triangles are similar.

5. Tales Theorem:

On any two lines that intersect parallel lines, the line segments separated by parallel lines are proportional.
