Polyhedrons are 3D shapes made of polygons joined at their edges. They have three properties: faces, which are the polygons; edges, where faces meet; and vertices, where edges meet. A convex polyhedron is one whose faces are convex polygons. Euler's Polyhedron Formula states that for any convex polyhedron: F + V - E = 2, where F is the number of faces, V is the number of vertices, and E is the number of edges. This formula is proven using induction and properties of interior and exterior polygon angles.

For a regular polygon, where all sides and angles are equal, the outer angle is calculated by dividing the total outer angle sum of 360 degrees by the number of sides. Some examples provided include calculating the sum of angles of a 12-sided polygon as 1800, the outer angle of a 20-sided regular polygon as 18 degrees, and determining that a regular polygon with an outer angle of 60 degrees would have 6 sides.

- There are methods to convert between rational numbers written as decimals and as fractions by multiplying or subtracting terms and solving for the value of the decimal. Geometric constructions can also represent irrational numbers.

010 lesson 2
The document defines three key properties of addition:
1) The 0 Property of Addition states that any number added to 0 is equal to the original number, such as 8 + 0 = 8.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
