In triangle xyz, a is the midpoint of xy, b is the midpoint for yz, and c is the midpoint of xz. also,
ay = 7
bz = 8
xz = 18
what is the perimeter of triangle abc?

Perimeter of Δ ABC = 7 + 8 + 9 = 24 cm

Step-by-step explanation:

In  triangle Δ XYZ ,

A is the mid point of XY

B is the midpoint of YZ

C is the mid point of XZ

AY = 7

BZ =8

XZ = 18

The mid - point theorem states that,

The segment formed by connecting two mid - points of a triangle is parallel to the third side and half as long

AY = 7 then BC = 7 cm

BZ = 8 then AC = 8 cm

XY = 18 then AB = 9 cm

Perimeter of Δ ABC = 7 + 8 + 9 = 24 cm
