Reason is that a square has all the aspects of a parallelogram a rectangle and a rhombus. It gets its congruent diagonals from the rectangle which is congruent
I am confident that the answer is C. 53.7
Slope is rise over run, aka change in y divided by change in x:

Answer: -1
Step 
<u>Find the value of x</u>
we know that
m∠FLI=m∠FLG+m∠GLH+m∠HLI ---------> equation 
In this problem we have
m∠FLI=
°
m∠FLG=
°
m∠GLH=
°
m∠HLI=
°
Substitute the values in the equation 

Combine like terms



°
Step 
<u>Find the value of each angle</u>
Substitute the value of x in each angle
m∠FLG=
°
m∠GLH=
°
m∠HLI=
°
therefore
<u>the answer is</u>
The smallest angle in the diagram is
