Copy each three-dimensional figure and with coloured pencils outline the triangles listed. What postulate proves that these triangles are congruent?

Given: pyramid with square base;
Show: ,
Draw an isosceles triangle and then join the midpoints of its sides to form another triangle. What can you deduce about this second triangle? Explain.
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.

In the following figure, the two-triangle shown are congruent. Then explain the following statement.
Deduce that
