Question Propeller Blade Angle

From Jeppesen Private Pilot Manual:

"If the angle of each section of a propeller were averaged, you could determine an overall blade angle. A propeller with a low blade angle, known as a climb propeller, provides the best performance for takeoff and climb, while one with a high blade angle, known as a cruise propeller, is more adapted to high speed cruise and high altitude flight."

Wouldn't you want a high blade angle for takeoff and climb, as this would give you a bigger bite of the air? Wouldn't you want a flatter propeller with a low blade angle for cruising flight? I asked a pilot about this, and he said a low blade angle means high pitch vice versa? Aren't propeller pitch and blade angle interchangeable terms?
