Provide an appropriate response.Use a compass and straightedge to construct a triangle DEF such that ?DEF ? ?ABC, where triangle ABC is the one shown below.
What will be an ideal response?
Answers will vary. A sample correct response would be as follows.
Start with a line segment DE congruent to AB. Then use the compass to measure off the distance AC, and draw an arc from D of this distance. Similarly, draw an arc of distance BC from E. The intersection of the two arcs yields the third point F of the triangle.
