Determine if the following triangles are congruent

∆ABC ≅ ∆EFD by the SSS Congruence Theorem.

Step-by-step explanation:

The digram shows that 3 sides of ∆ABC are congruent to the 3 sides of ∆ EFD.

Based on the Side-Side-Side Congruence Theorem (SSS), we can conclude that both triangles are congruent to each other.

Therefore:

∆ABC ≅ ∆EFD by the SSS Congruence Theorem.

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.
