Unit 3: Geometry of Shapes & Space: Exploring Form and Measurement
This chapter explores the essential properties and relationships of geometric shapes in both two and three dimensions. It covers key concepts such as angles, polygons, and the Pythagorean theorem, along with practical applications for measuring areas, perimeters, volumes, and surface areas of various shapes. By understanding these concepts, students will gain the ability to analyze and design structures in physical and abstract spaces.

What we have learnt
- Angles on a straight line add up to 180 degrees.
- The sum of the interior angles of a triangle is always 180 degrees, while for a quadrilateral it is 360 degrees.
- Pythagoras' Theorem relates the lengths of the sides of a right-angled triangle.
Key Concepts
- -- Angles
- Measurements formed by two rays sharing a common endpoint, measured in degrees.
- -- Polygon
- A closed two-dimensional shape with straight sides.
- -- Pythagorean Theorem
- A fundamental theorem in geometry that states that in a right triangle, the square of the hypotenuse length is equal to the sum of the squares of the other two sides.
- -- Area and Perimeter
- Perimeter is the total distance around a shape; area is the measure of the space within a shape.
- -- Volume
- The amount of space that a three-dimensional object occupies.
- -- Surface Area
- The total area of all the surfaces of a three-dimensional object.
