Study Notes
Algebraic Expressions
- Simplifying algebraic expressions involves combining like terms to reduce complexity.
- Like terms are terms that have the same variable raised to the same power, allowing them to be added or subtracted.
Triangle Angles
- The sum of the interior angles of a triangle is always 180 degrees.
- True statement: The angle sum of a triangle equals 180 degrees.
- True statement: Any exterior angle of a triangle equals the sum of the two opposite interior angles.
Quadrilateral Angles
- The angle sum of a quadrilateral is 360 degrees.
Angle Properties with Transversal
- When two straight lines are crossed by a transversal, corresponding angles and alternate interior angles demonstrate properties of angles.
Solving Linear Equations
- Techniques to solve simple linear equations may include isolating the variable using addition, subtraction, multiplication, or division.
Symmetry
- Line symmetry, also referred to as reflection symmetry, occurs when a line divides a shape into two mirror-image halves.
Coordinate System
- The number plane is also known as the Cartesian plane, a coordinate system that uses two perpendicular axes to identify points in space.
