Ответ:
Given
BC bisects ABD
∠ ABD =52°
prove: m ∠ABC=26°
To proof
As given in the question
BC bisects ∠ABD
This means BC divided ∠ABD into the two equal parts.
Therefore
As given
∠ABD = 52°
put this in the above value
we get
∠ABC = 26°
Hence proved
Ответ:
An angle bisector divides the angle into equal halves.
Given that:
From the question, we understand that:
BC bisects![\angle ABD](/tpl/images/0057/5683/4dc27.png)
This means that:
So, we have:
Divide both sides by 2
So, we have:
Hence,
