Question
Explain how you can prove BC = DC
Hint:
Find the congruence rule used and then find the equal sides.
The correct answer is: ⇒ BC = DC (corresponding parts of congruent triangles)
Complete step by step solution:
Consider 2 triangles, and
From the figure, we have
AB = AD (given)
∠ BAC = ∠ DAC (given)
Also, AC = AC (common side)
∴ △ABC ⩭ △ADC by SAS congruence rule.
