Given δcab ≅ δedf, complete the sentences below. in δcab, the measure of line bc is 4 units, and the measure of line ac is 5 units. in δedf, the measure of line de is 3x + 2 units, the measure of line ef is y units, and the measure of line df is 2x + y units. the measure of line de is __ units. the measure of line ef is __ units. the measure of line df is __ units.

The measure of line DE is 5 units.

The measure of line EF is 4 units.

The measure of line DF is 6 units.

Step-by-step explanation:

Given: ΔCAB ≅ ΔEDF

By CPCTC, corresponding sides both triangle are congruent.

Therefore

AC=DE.....(1),

AB=DF...(2),

BC=EF.........(3)

From (1),

DE=5 units

From (3)

EF=4 units

⇒ y= 4units

Now, DF= 2x+y=2(1)+4=6 units

Therfore, from (2), AB= 4 units.
