Answer 2

Answer:

hi Mr.Rory

Explanation:

If in ΔABC and ΔDEF, AB || DE, BC = EF and BC || EF, vertices A, B, C are joined to vertices D, E, F respectively, then quadrilateral ABED is a parallelogram, quadrilateral BEFC is a parallelogram, AD || CF and AD = CF, quadrilateral ACFD is a parallelogram, AC = DF, and △ABC ≅ △DEF.

hope it will help you
