Knowing that ΔQPT ≅ ΔARZ, a congruent angle pair is: ∠Q ≅ ∠R
∠P ≅ ∠A
∠T ≅ ∠Z
∠P ≅ ∠Z

∠T ≅ ∠Z

Explanation:

Find the corresponding angles: Q = A               P=R &          T=Z

Therefore, the congruent angle pairs are T and Z

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
