QUESTION: Rowena is proving that AD ≅ EB. Which statement does
the ♣ represent in her proof?
Ans: A. ΔACD ≅ ΔECB
QUESTION: Complete the paragraph proof.
We are given AB ≅ AE and BC ≅ DE. This means ABE is an isosceles
triangle. Base angles in an isosceles triangle are congruent based on
the isosceles triangle theorem, so ∠ABE ≅ ∠AEB. We can then
determine △ABC ≅ △AED by . Because of CPCTC, segment AC is
congruent to segment . Triangle ACD is an isosceles triangle based
on the definition of isosceles triangle. Therefore, based on the
isosceles triangle theorem, ∠ACD ≅ ∠ADC.
