To Prove : For the given figure,
Explanation of Solution
Given information:
According to SAS similarity theorem;
Now consider one triangle has vertices A, B, and C and another triangle has vertices S, R, and A.
All the corresponding sides are in proportions,
Therefore, according to the SSS similarity theorem,
Now if the lines BC and AR are parallel then the
And as the
Thus,
The angles
Therefore, the lines BC and AR are parallel.
Hence,
