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

Option A. <A≅<D.

Step-by-step explanation:

Two triangles are congruent by SAS congruence property if two sides and the angle between the two equal sides is congruent in both the triangles.

It is given the  sides  AB ≅ DE and AC≅DF in triangles ABC and DEF.

The angles between these equal sides are <A and <D .The triangles will be congruent by SAS if <BAC ≅<EDF.

Option A. <A≅<D. is the correct ption.

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
