A. are the length of a side of a square and the perimeter of the square related proportionally? why or why not?
b. are the length of the side of the square related proportionally? why or why not?

The answer is yes.

Step-by-step explanation:

Yes, the length of a side of a square and the perimeter of the square are related proportionally.

Let the side of the square be a.

So, perimeter is given as =

Or we can say =

We can see, that the perimeter is always 4 times the side length of the square.

Example:

Suppose the side of the square is 4 cm.

So, perimeter = cm

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
