Solution
Solution Steps
Step 1: Analyze the given information
Triangles FAD and DCE are translations of triangle ABC. This means that corresponding angles and sides of these triangles are congruent.
Step 2: Evaluate statement A
Points B, A, and F are collinear. Since FAD is a translation of ABC, and translations don't change the relative positions of the vertices within a shape, F cannot lie on the line segment BA. Hence, this statement is false.
Step 3: Evaluate statement B
The measure of angle BCA is the same as the measure of angle ECD. Since triangle DCE is a translation of ABC, the corresponding angles are congruent: ∠BCA ≅ ∠DCE. Hence, this statement is false since ECD is being compared in the given option instead of DCE.
