Solving Geometric Problems

Solving Geometric Problems


Example Question


- \(O P=O A+\frac{1}{3}A B\)
- \(=OA+\frac{1}{3}(OB-OA)\)
- \(=\frac{2}{3}OA+\frac{1}{3}OB\)
- \(=\frac{2}{3}a+\frac{1}{3}b\)

Ex 11E


- \(XY =\mathbf{b-a}\)
- \(YZ=\mathbf{c-b}\)
- If XY and YZ are the same, then \(b-a=c-b\)
- Rearranging: \(\mathbf{a+c=2b}\)
