Jada claims that B′C′D′ is a dilation of BCD using A as the center of dilation.What are some ways you can convince Jada that her claim is not true?[img]https://cdn.openupresources.org/uploads/pictures/8/8.2.A.PP.Image.17.png[/img]
Answers vary. Below is a list of things which would have to be true if B′C′D′is a dilation of BCD using A as the center of dilation. Any measurement which showed any of these to not hold is a complete answer.[list][*]m∠BCD=m∠B′C′D′[/*][*]A, B, and B′ should be collinear.[/*][*]A, C, and C′ should be collinear.[/*][*]A, D, and D′ should be collinear.[/*][*]B′C′ should be parallel to BC.[/*][*]C′D′ should be parallel to CD.[/*][/list]
