Parallelograms and Vectors
Saturday, March 15th, 2008“Again with the maths…” Thursday on the train home, I was trying to solve a maths exercise - I am given A, B and C. I was asked to solve D so that ABCD formed a parallelogram. Where did I start? Here’s what I originally thought:
- kBC = AD (The top and bottom edges should be parallel)
- |AB| = |CD| (The two sides would be the same length)
I couldn’t think of any more rules to help me, so I gave made a note of it, then moved on. It wasn’t long until I’d be at it again, and this time I’d solve it. (more…)
