PA/AQ = PB/BR We know that, if a line divides any two sides of a triangle in the same ratio, then the line is parallel to the third side. Therefore, AB || QR. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerLeave an answerCancel reply Featured image Select file Browse Add a Video to describe the problem better.
