STANDARD 4: Students prove basic theorems involving congruence and similarity. ESTÁNDAR 4: Los estudiantes prueban teoremas que involucran congruencia y semejanza. STANDARD 5: Students prove that triangles are congruent or similar, and they are able to use the concept of corresponding parts of congruent triangles. ESTÁNDAR 5: Los estudiantes prueban que son triángulos congruentes o semejantes y son capaces de usar el concepto de partes correspondientes de triángulos congruentes.

4
These are examples of POLYGONS: These are NOT POLYGONS: A POLYGON is a closed figure in a plane which is made up of line segments, called sides, that intersect only at their endpoints, named vertices. Standards 4 and 5

5
A TRIANGLE is a three-sided polygon Standards 4 and 5

A A m = 180° B B m + C C m + If and A = 90 ° m then = 180° B m + C m + 90° - 90° -90° = 90° B m C m + Conclusion: In a right triangle, both non- right angles are acute and complementary! What kind of angles are the non-right angles in a right triangle?
