Grade 8 Geometry

The video lectures for Grade 8 geometry cover the concepts of congruence and similarity. Congruence in rotation, reflection, and translation is demonstrated experimentally and by using coordinates on a 2D plane. Through these videos, students will also learn to prove congruence between two congruent figures. The concept of similarity is demonstrated, and a sequence is discussed to illustrate the similarity between two 2D figures. Also, the criterion for similarity of triangles is established using informal arguments. Grade 8 learners also get introduced to the derivation and application of the Pythagorean Theorem. Finally, student viewers of these video lectures would also learn the formulas for volumes of cones, cylinders, and spheres in detail.
