8-88.

For each pair of triangles below, decide if the triangles are congruent. If the triangles are congruent:  

  • State which triangle congruence property proves that the triangles are congruent.

  • Write a congruence statement (such as  ).

  1. Triangle A, B, C and triangle B, C, D are connected to form a quadrilateral with side B, C, in common. Angle A and angle D are each marked with two arcs. Side A, B and side C, D are each marked with one arrow.

    What parts of these triangles makes them congruent? Do they share any parts?

    AAS ,

  1. Segments, A, E, and B, D intersect at point C, sides, B, C and C, D, each have 1 tick mark, Angle B and Angle D each is 90 degrees.

    Use the same method as part (a), but use a different congruence property.
    Are there unmarked corresponding parts that are congruent?
