As shown in the figure, BC = 20cm, De is the vertical bisector of line AB, intersects BC at point E, AC = 12cm, and calculates the perimeter of △ ace

As shown in the figure, BC = 20cm, De is the vertical bisector of line AB, intersects BC at point E, AC = 12cm, and calculates the perimeter of △ ace

∵ De is the vertical bisection of AB, ∵ be = AE. ∵ the perimeter of ACE = AE + EC + AC = be + CE + AC = BC + AC = 12 + 20 = 32 (CM)
