If triаngle 3 shоws а 100 degree rоtаtiоn of triangle 1 about point P, what is the degree of intersection of lines m and n? [50] degrees The diagram shows two intersecting lines labeled m and n, which cross at point P. Line m slants upward to the right, and line n runs from the lower left to the upper right. Three identical black triangles with different orientations, labeled 1, 2, and 3, are placed around the lines: Triangle 1 is located to the upper left of point P and line m, oriented upright, facing to the right. Triangle 2 is positioned between the lines above n and to the right of m, mirroring triangle 1. Triangle 3 is below n and to the right of point P, mirroring triangle 2. The image suggests rotation or transformation of a triangle in relation to the lines. This image also shows two [reflections] about lines m and then line l.  Select one: Reflections Rotations Translations
