Answer:
NOT PROPORTIONAL
Step-by-step explanation:
The given two fractions are:
and
.
Proportional fractions are those which have the same value when to reduced to the simplest form.
Consider two fractions
and
.
We say they are proportional if
.
Or, if
then we can say the fractions are proportional.
Here the fractions are:
and
.
LHS: 5 X 10 = 50.
RHS: 8 X 8 = 64.
Clearly they are not equal. So, we can say these two fractions are not proportional.
Answer: Congruent
Step-by-step explanation:
Line BC is reflexive to itself
AB is congruent to CD, and that's given
Line AC is congruent to BC, using these prior proofs
Angle EDC and Angle FAB are congruent, and that's a given.
You can conclude that they are congruent by AAS
