This paper proposes geometric representations to aid in understanding the relativistic phenomena of length contraction and time dilation. Using simplified trigonometric models, the Lorentz transformation and related effects can be visually represented on a semicircle. These tools illustrate how relativistic measurements of moving rulers and time intervals change based on velocity. The models help visualize how the observer's motion affects perception of time, and highlight relativistic simultaneity, time flow, and the role of light signal delay. The paper supports special relativity with visual models and stresses the importance of treating time as the fourth dimension for a deeper conceptual grasp.
