as theta doesn't follow triangle law of addition,but follows ordinary rules of algebra (2theta + 5theta -theta=6theta),it is a scalar quantity.

in case of electric current,it has got direction but it is a scalar quantity as it doen't follow triangle law of addition.

theta is neither scalar nor vector. It falls in another category called tensors.
as it does not follow triangle law of addition.
Try it by rotating your pencil box or book three times in diff orders

infinitesimal angular displacement delta theta is a vector quantity
while finite angular displacement theta is a scalar quantity
remember circular motion?

theta is a tensor as it does not follow the triangle law of vector addition but it does have direction

If theta is considered as an angular displacement then it is a vector quantity.
