Suppose you are given a scalene triangle and a point on some line localid="1648799479069" . How many triangles are there with one vertex at localid="1648799462577" , another vertex on localid="1648799472074" , and each triangle congruent to the given triangle?
Suppose you are given a scalene triangle and a point on some line . How many triangles are there with one vertex at , another vertex on, and each triangle congruent to the given triangle.
Decide whether you can deduce by the SSS, SAS, or ASA postulate that another triangle is congruent to . If so, write the congruence and name the postulate used. If not, write no congruence can be deduced.

A method that can be used to prove right triangles congruent, but cannot be used with other types of triangles, is themethod.
For exercises 16-19 draw and label a diagram. List in terms of the diagram, what is given and what is to be proved. Then write a two column proof.
If segments are drawn from the midpoints of the legs of an isosceles triangle perpendicular to the base, then those segments are congruent.
