How is the gate trigger resistor value calculated for a triac

As per the application notes of bta08-600cw, to control a three phase induction motor, for triggering the triac gate, the value of resistor is shown as 510 ohm. How is this value arrived at? What would be the resistor wattage? enter image description here From the From the data sheet, which quadrant to be considered to know the gate trigger current? enter image description here Also for three phase supply, how is the voltage shown as 220v instead of 440v(in the schematic diagram)?

Can the gate be triggered with either AC or DC? If so what is the impact of calculating the resistor value in both these cases?
