likely questions for vectors and geometry and answers
This still isn't a question. You haven't even mentioned what level of maths you're talking about.

but can you help me solve it
ABC is an equilateral triangle of side 3 units. The points P, Q lie on BC, CA
respectively and are such that AQ = CP = 2units. If the point R lies on AB
produced so that BR = 1unit, prove that P, Q, R are collinear.

Since you're new to the maths forum, I suggest reading the maths forum posting guidelines to start (sticky thread at the top of the forum). We don't provide worked solutions, rather help you to get to the solution yourself.

That said, I suggest drawing a diagram, then find expressions for QP and PR, expressing everything in terms of a linear combination of AC and AB.

If you can show those two are parallel, and then since they have a point in common, they must be collinear.

Post any working so far, if you get stuck
