Difference in Strains

I still don't quite understand the different between steric, angle, and torsional strain?

Steric– strain between non bonded atoms that occupy the same space
ex) flag pole hydrogens in the boat conformation
Torsional strain– strain due to rotation where there is a lot of repulsion. a force opposes rotation of a part of a molecule about a bond
ex) CH3-CH3 eclipsed
bond strain- when a bond is not at its ideal angle
ex) cyclopropane at 60 degrees
