Defining irrational numbers and understanding how they fill the gaps on the number line to create the set of real numbers.
Extending the rules of exponents to include rational powers and simplifying complex radical expressions.
Algebraic Structures
Mastering the manipulation of polynomials and understanding the relationship between algebraic factors and zeros.
Utilizing the Factor Theorem and Remainder Theorem to break down higher degree expressions.
Modeling real world scenarios using linear equations and visualizing solutions on a Cartesian plane.
Logic and Euclidean Geometry
Building a foundation of deductive reasoning through the study of axioms, postulates, and geometric proofs.
Introduction to Euclid's definitions and the necessity of unproven statements in a logical system.
Proving properties of angles formed by transversals and the internal angles of polygons.
Congruence and Quadrilaterals
Investigating the criteria for triangle congruence and the hierarchical properties of four sided figures.
Deep dive into SAS, ASA, SSS, and RHS rules to determine when two triangles are identical.
