does anyone know how to do two column proofs? someone that can help?!
Yes, but would need to see the diagram (clearly), and the Given..and what you want to prove.
If you just want general guidelines there is an example here: http://www.sparknotes.com/math/geometry3/geometricproofs/section1.rhtml The table on the bottom is an example to a 2 column proof of the diagram above.
i have one i need help on .. here
the given is line BF is perpendicular to line HD and line GC is perpendicular to line AE
what i need to prove is that angle BAH is congruent to angle CAE
As I said, a diagram MUST be included!
\[ BF \perp HD \quad\;\quad | \quad \text{given} \\ \angle BAH = 90^\circ \quad | \; \text{Angle between 2 perpendicular lines is } 90^\circ \\ GC \perp AE \quad\;\;\quad | \quad \text{given} \\ \angle CAE = 90^\circ \quad | \; \text{Angle between 2 perpendicular lines is } 90^\circ \\ \angle BAH = \angle CAE = 90^\circ \] Is that ok?
@Easyaspi314 a diagram is included look above ^^^^
