Answer:
Associative Property of Addition
Step-by-step explanation:
From the list of given options, option A correctly answers the question and this is because
--- (1)
or
--- (2)
<em>The above illustrations only apply to Associative Property of Addition</em>
In Crystal's case:
This can be compared to (1) above
Hence;
<em>Option A answers the question</em>
Answer:
Given :
ABC is a right triangle in which ∠ABC = 90°,
Also, Legs AB and CB are extended past point B to points D and E,
Such that,
To prove :
Proof :
In triangles AEC and EBA,
∠EAC= ∠ABE ( right angles )
∠CEA = ∠AEB ( common angles )
By AA similarity postulate,
,
Similarly,
Now, In triangles ADC and CBD,
∠ACD = ∠CBD ( right angles )
∠ADC= ∠BDC ( common angles )
By AA similarity postulate,
,
Similarly,
From equations (1) and (2),
The corresponding sides of similar triangles are in same proportion,
Hence, proved....
