Question

△ABC​ ​ is to form ​ ​△A′B′C′​ ​ .

Answer 1

The corresponding sides and angles of △ABC and △A'B'C' are equal in measure. This means that for each side and angle in △ABC, there is a corresponding side and angle in △A'B'C' that is congruent to it. This relationship preserves the overall shape and size of the triangle, just in a different position or orientation.
