Theresearch followed the five stages of the ADDIE development model, namely. Analysis, Design,Development, Implementation, and Evaluation. The results of the expert validation for media and contentshowed that the developed e-module fell into the "valid" category, with average scores of 3.36 and 3.37,respectively. The practicality tests also yielded excellent results, with a practicality percentage of 92.50%from teachers and 89.49% from students, both categorized as "very practical." Therefore, this e-modulewas considered suitable and effective for use as a learning resource, particularly for teaching thePythagorean Theorem.
