We obtain brane inflation in configurations with Dp and D(p-2) branes which are far apart and almost perpendicular to each other. Chaotic brane inflation occurs when the branes can only rotate with the inflaton given by the angle between the branes. When the branes can also move hybrid brane inflation occurs where the inflaton is the distance between the branes and the trigger field is related to the angle. In both models we find a spectral index very close to one. Both types of inflation require $M_s \sim 10^{16-17} GeV$ with one large radius of size $1/R \sim 10^{12-15} GeV$.
