Part A This is the start of an explanation of how to plan a coordinate proof that all equilateral triangles are similar. Choose the vertices necessary
Show that an equilateral triangle with side length a can be placed on the coordinate plane with these vertices.

Part B
Choose the words to finish the explanation of how to plan a coordinate proof that all equilateral triangles are similar.
Show that an equilateral triangle with side length a can be placed on the coordinate plane with the vertices specified above. Similarly place an
equilateral triangle with legs having length b on the coordinate plane. Show that there exists a reflection y that maps one triangle
onto the other
