hello! i apologise if this stupid.
i am following the 2 month plan and currently on the geometry section. after finishing triangles 1 and 2 (as well as the practice), i noticed that there was no content on congruence? similarity was discussed but i didn’t hear about congruence anywhere. i’ve now started quadrilaterals and i’m wondering if it comes up later in the plan or would i have to supplement that topic from somewhere else? did i miss something?
