7-86.

Para cada una de los siguientes puntos, determina si los dos triángulos más pequeños de las figuras son congruentes. De serlo, crea un diagrama de flujo para explicar por qué. Si los triángulos no son congruentes, explica por qué no. Dibuja nuevamente y etiqueta los diagramas cuando sea necesario.  

Cada conjunto de triángulos es congruente. Ahora muestra por qué o de qué manera.

  1. A quadrilateral divided into two triangles by a diagonal. The left side is 6 x + 6, the right side is 8 x + 2, and the bottom side is 12 x minus 2. The top and bottom sides are both marked with two tick marks. The alternate interior angles are both marked with one tick mark.
