Step-by-step explanation: 5 17 21 53

All of the sides are the hypotenuses of 3 by 4 right triangles, so

   3² + 4² = 5²   the sides are 5 units long    s = 5

   P = 4s  for a square

   P = 20

   area square = s²

   Area = 25

glide reflection.

its mainly because the pattern will be infinite and will never end. it will look like a gilder or like a filpbook when set to motion.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
