The left one
The two triangles are congruent because they apply the rule of S-A-S (side - angle - side)
side AB = side AD
angle BAC = angle DAC
side AC on triangle 1 = side AC on triangle 2

The right one
The two triangles are congruent because they apply the rule of R-H-S (right angle - hypotenuse - side)
angle HGJ = angle JLK
hypotenuse GJ = hypotenuse LJ
side HJ = side JK

ΔABC and ΔXYZ are similar triangles. The lengths of two sides of each triangle are shown. Find the lengths of the third side of
Norma-Jean [14]

Answer:

b=9

x=5.5

Step-by-step explanation:

find the common ration

AB is 6, and XY is 3 (they are the corresponding sides)

ratio is 2 to 1 (6/3=2/1)

AC corresponds with YZ

XY is 4.5 so b is 4.5*2=9

ZY corresponds with CB

CB is 11, since XYZ is the smaller divide by 2 instead of multiplying by 2
