2-94.

Determine which similarity conditions ( or ) could be used to establish that the following pairs of triangles are similar. List as many as you can.

  1. Two triangles. Triangle at left with side lengths 3, 5, and 4. Triangle at right with side lengths 3.6, 6, and 4.8.

    See the Math Notes box in Lesson 3.2.5 for extra help.

    Pay attention to the angles as well as the side lengths.

  1. Two triangles. Triangle at left labeled as follows: left side, 2, bottom side, 3.5, left bottom angle, 80 degrees, right bottom angle, 30 degrees. Triangle at right labeled as follows: left side, 4 , bottom side, 7, left bottom angle, 80 degrees, right bottom angle, 30 degrees.

    See part (a).

  1. Two triangles. First triangle, left side is 4, top angle is 40 degrees, Second triangle, top left side is 4, top angle is 40 degrees.

    Not enough information is given to establish similarity. No similarity condition can be used.
