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.

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.
In an isosceles triangle, if the angle between the congruent sides is bisected, then two congruent triangles are formed.
