You and some neighbors are landscaping
a community park. the organizer of the project chooses an
area for two congruent triangular rock
gardens. you agree to be in charge of placing the
pieces of wood to outline the gardens. the only tools you have are one saw, a
protractor, and two very long pieces of wood. using detailed steps, describe one way to guarantee that the triangular outlines will
be congruent. justify your answer. explain why the
triangles must be congruent. draw diagram(s) to support your solution
