What are the side lengths of the original triangle, ΔABC?
Find AB by using the Pythagorean Theorem. For this triangle, (AC)2 + (CB)2 = (AB)2.
What are the side lengths of the enlarged triangle, ΔA′B′C′?
Find A′B′ by using the Pythagorean Theorem.
A′C′ = 6, B′C′ = 8, A′B′ = 10
Calculate the area and the perimeter of ΔA′B′C′.
