Question

if ΔABC = ΔDEF, which congruences are true by CPCTC? Check all that apply.A. ∠A ≅ ∠DB. AB ≅ DEC. ∠E ≅ ∠CD. AC ≅ DFE. ∠B ≅ ∠FF. BC ≅ DE

Answer 1

To answer the question, let's begin by defining the term CPCTC. CPCTC is an abbreviation that stands for "Corresponding Parts of Congruent Triangles are Congruent".

$\begin{gathered} \Delta ABC=\Delta DEF \\ |AB|\equiv|DE| \\ |BC|\equiv|EF| \\ |AC|\equiv|DF| \\ \angle A\equiv\angle D \\ \angle B\equiv\angle E \\ \angle C\equiv\angle F \end{gathered}$

As such, options A, B, D are the correct answers
