Study Notes
Straight Line Graphs
- Straight line graphs display linear relationships between variables.
- The equation is typically written as y = mx + b, where:
- 'm' is the slope (gradient)
- 'b' is the y-intercept.
- The graph is a straight line.
- Understanding slope and intercept helps analyze the relationship.
Forming and Solving Equations
- Equations can be formed from word problems or real-world situations.
- The goal is to find unknowns.
- Methods include substitution, elimination, and using algebraic principles to simplify and solve.
Testing Conjectures
- Conjectures are hypotheses or educated guesses.
- Testing involves verifying if a statement is true in all cases.
- Used are logical reasoning, proofs, or counterexamples.
Three-Dimensional Shapes
- Three-dimensional shapes have depth, length, and width.
- Examples include cubes, spheres, cones, and pyramids.
- Properties include volume, surface area, relationships between faces, edges, and vertices.
Constructions and Congruency
- Geometric constructions use a compass and straightedge to draw shapes.
- Congruent figures match in shape and size.
- Congruence proofs demonstrate identical dimensions and angles.
