Question

Triangle ABC has side lengths:

AB = 3.5 cm, BC = 2.4 cm, and AC = 4.2 cm

ΔABC ≅ ΔHJK

What is the length of side HJ?

Answer 1

Answer: 3.5 cm

Explanation:

match up the letters: ΔABC ≅ ΔHJK

• ANGLES
• ∠A ≅ ∠H
• ∠B ≅ ∠J
• ∠C ≅ ∠K

• SIDES
• AB ≅ HJ
• BC ≅ JK
• AC ≅ HK

Since AB ≅ HJ and AB = 3.5 cm, then HJ = 3.5 cm
