10-69.

En primer lugar, decide si los siguientes triángulos son semejantes. Luego, si son semejantes, usa la información en cada diagrama para resolver para .

  1. Two triangles with same orientation, labeled as follows: Larger triangle D, E, F: Side, e, d, 9, Side, D, F, 6, and side, E, F, x. Smaller triangle, A, B, C, side, A, B, 6, side, A, C, 4, and side, B, C, 7.

    Si solo dos pares de lados correspondientes tienen razones iguales, ¿puedes concluir que los triángulos son semejantes?

  1. Large triangle has a segment that appears to be parallel to the base creating a smaller triangle inside. The segment has length, 7, and the base of the large triangle is, x. The left side of the large triangle has 2 sections with lengths 12 on top and 4 on bottom. The right base angle, of each triangle, is marked to show they are congruent.
    ¡Cuidado!

    Los dos triángulos son semejantes (según ).

    Dibuja dos triángulos separados. Luego, escribe una proporción y despeja la .
