ΔABC has sides AB = 5 cm, BC = 6 cm, and AC = 7 cm. ΔXYZ is congruent to ΔABC. What is the perimeter of ΔXYZ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 18 cm.
If two triangles are congruent, their corresponding sides are equal in length.
Perimeter of ΔABC = 5 + 6 + 7 = 18 cm
So, the perimeter of ΔXYZ is also 18 cm.
