The AB side of the ABC triangle is half the size of the BC side, the AC side is 2cm larger than the BC side. Re-measure the ABC triangle if it is known that BC = 6 cm.
1) We find out how long the AB side has, if it is known that the BC side is 2 times longer, and the BC length is 6 cm.
6/2 = 3 cm.
2) Find out how long the AC side is, if it is known that the BC side is 2 cm shorter and the BC length is 6 cm.
6 + 2 = 8 cm.
3) Let’s find out what perimeter the triangle has, if we found all its sides and they made AB = 3 cm, AC = 8 cm and BC = 6 cm.
3 + 8 + 6 = 17 cm.
Answer: The perimeter of triangle ABC was 17 cm.
