Most definitely not, as resistance, reactance, and impedance are not themselves phasor quantities. However, it is derived from a phasor diagram (by dividing a voltage phasor diagram by the reference phasor, current).

What is a phasor diagram and why you draw it?
Theoretically, it can be drawn at any angle. Normally, however. it is drawn along the real, positive, axis (i.e. facing East). For series circuits, the reference phasor is the current and, for parallel circuits, the reference phasor is the voltage. For transformers, it is the flux.
Why must you add the resistance and reactance of a circuit in series by the phythagorean method in order to find the total impedance?
The resistance and reactance of an a.c. load are determined from the phasor diagram for that load. A phasor diagram is very similar to vector diagram, and represents the voltage drop across the resistive component of the load as being in phase with the load current, and the voltage drop across the reactive component as lagging the load current by 90 degrees. The vector sum of these two voltage drops will equal the value and phase-relationship of the supply voltage.If we now divide each of these three voltages by the supply current, we will converted the phasor diagram into what is called an 'impedance triangle', in which the resistance is represented horizontally, the reactance is represented vertically, and the impedance is represented by the resulting hypotenuse. So, to find the hypotenuse (i.e. the impedance) we must use Pythagoras's Theorem to vectorially-add the horizontal (resistance) and vertical (reactance) components.

What is impedance diagram?
An impedance diagram (sometimes called an impedance triangle) results when a series circuit's voltage phasor diagram is divided throughout by its reference phase (current) -this results in resistance (=VR/I), inductive reactance (=VL/I), capacitive reactance (=VC/I) and impedance (=V/I) andillustrates the Pythagorean relationship between the circuit's impedance, reactance, and resistance.

What is impedance triangle?
An impedance triangle has resistance (always positive) in the x axis and reactance (at a right angle to resistance) in the y axis. The line that completes this triangle (the hypotenuse) is the absolute value of the impedance.

What is the physical significance of the impedance?
Impedance may refer to: the ratio of the voltage phasor to the electric current phasor, as in Electrical impedance, a measure of opposition to time-varying electric current in an electric circuit. Characteristic impedance, a measure of opposition to electric current propagation in a transmission line. Impedance matching and Impedance mismatch. Vacuum impedance, a universal constant. Electromagnetic impedance, a constant related to electromagnetic wave propagation in a medium. Mechanical impedance, a measure of opposition to motion of a structure subjected to a force. Acoustic impedance, a constant related to the propagation of sound waves in an acoustic medium. Linear response function, a general way to represent the input-output characteristics of a system. Scroll down to related links and look at an example: "Interconnection of two audio units".
What are the phasor diagrams and sinusoidal expressions of the three voltages?
The Phasor diagram explains the relation between voltage and current. This comparison happened in the Sinusoidal functions and solved using the Sinusoidal expression.
