∆abc and ∆fde are congruent by the criterion. (use the three-letter abbreviation without spaces.)
the value of x is , and the value of y is .

x = 11, y = 8

Step-by-step explanation:

ΔABC and ΔFDE are congruent by the postulate SSS

Equate the congruent sides in the 2 triangles

BC = ED, that is

x + 3 = 14 ( subtract 3 from both sides )

x = 11

DF = AB, that is

x - y = 3 ← substitute x = 11

11 - y = 3 ( subtract 11 from both sides )

- y = 3 - 11 = - 8 ( multiply both sides by - 1 )

y = 8

The value of x is 11 and the value of y is 8.

Step-by-step explanation:

It is given that ∆ABC and ∆FDE are congruent.

The corresponding parts of congruent triangle are congruent.

                      (CPCTC)

                .... (1)

                      (CPCTC)

Subtract 3 from both the sides.

The value of x is 11.

Put x=11 in equation (1).

Add y on both the sides.

Subtract 3 from both the sides.

The value of y is 8.
