What else would need to be congruent to show that abc def by aas?

The correct answer is A. ∠A = ∠D

Step-by-step explanation:

To prove any two triangles congruent by using the AAS congruency postulate we need to show corresponding two angles and one corresponding side of the two triangles are equal.

Now, to show ΔABC ≅ ΔDEF by AAS congruency postulate,

∠ACB = ∠DFE = 30° ( From the given figure)

∠ABC = ∠DEF ( It should be equal if the triangles are to proved congruent by AAS rule)

AB = DE = 10 units ( From the given figure)

So, ΔABC ≅ ΔDEF by AAS congruency rule.

Hence, The correct answer is A. ∠A = ∠D

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
