Question

What is needed to prove triangleBCA is congruent to triangleEFD by ASA (angle-side-angle) ?
-AB is congruent to DE
-triangleF is congruent to triangleC
-BC is congruent to FE
-triangleB is congruent to triangleE

Answer 1

m<C = m<F

Answer 2

to prove it to be congruent using ASA
we observe from the figure that angle A is equal to angle D
and side AC=FD
now the other angle is C and F
we need to prove that angle C = angle F
i think second option should be angle not triangle

Answer 3

ya you're right , my bad .
