<span>The reflexive property of equality states that a value is equal to itself. (i.e. for all real numbers, x = x.</span>)
Given that the reason for the missing statement, it means that the similarlity statement is equal to it self.
Having proved in statement 3 that <span>∠AEC ≅ ∠BDC both being right angles, it can be seen that the angle both have in common is angle C.
Thus, to statement 4 shows that angle C is congrent to itself.
Therefore, the missing statement in step 4 is </span><span>∠ACE ≅ ∠ACE</span>
Answer:
The three sides have the same length.

Answer:
Step-by-step explanation:
z=xi+yj
x=-1.2=r cosθ (say)
y=-1.6=r sinθ(say)
square and add
r²cos²θ+r² sin ² θ=(-1.2)²+(-1.6)²=1.44+2.56=4
r²=4
r=2
divide
tanθ=y/x=-1.6/(-1.2)=16/12=4/3
θ=tan ^{-1}(4/3)≈53.13°
so polar coordinates are (2,53.13°)
