Pythagorean Theorem 3D - Double Triangle - Dimensions to Hypotenuse

This math topic involves practicing the Pythagorean Theorem in a three-dimensional space, focusing on double triangles and calculating the hypotenuse between two points. Specifically, the problems require finding the distance from point A to point D on pairs of triangles, presumably applying the theorem consecutively in a multistep 3D spatial reasoning context. Each question provides an image of the geometric setup and multiple answers, from which the correct one needs to be chosen. This forms part of an introduction to the Pythagorean Theorem in 3D.
