Triangle ABC is transformed to obtain triangle A'B'C':
A Coordinate grid (plane, graph, whichever one you like to use) with two triangles on it. Triangle ABC and Triangle A'B'C'. Chart below tells you where the points are placed:
ABC / A= (-12, 12) / B= (-9, 6) / C= (-3, 12)
A'B'C' / A'= (4, -4) / B'= (3, -2) / C'= (1, -4)
Which statement is correct for â–²ABC and â–²A'B'C'?
1. â–²ABC ~ â–²A'B'C' because â–²A'B'C' is obtained by dilating â–²ABC by a scale factor of 1/3 and then rotating it about the origin by 180 degrees.
2. â–²ABC ~ â–²A'B'C' , because â–²A'B'C' is obtained by dilating â–²ABC by a scale factor of 1/4 and then rotating it about the origin by 90 degrees.
3. â–²ABC ~ â–²A'B'C' , because â–²A'B'C' is obtained by dilating â–²ABC by a scale factor of 1/4 and then rotating it about the origin by 180 degrees.
4. â–²ABC ~ â–²A'B'C' , because â–²A'B'C' is obtained by dilating â–²ABC by a scale factor of 1/6 and then rotating it about the origin by 90 degrees.
