Answer:
a). Figure A and C
b). Figure D and F
Explanation:
a). From the given figures, sides of figure (A) and figure (C) appear to be congruent.
Therefore, pair of triangles A and C will be congruent by SSS property of congruence.
b). If two figures are similar, their corresponding sides will be proportional.
Since sides of the rectangles given in figures (D) and (F) are proportional, both will be similar.
