Study Notes
Quadrilaterals
- A square has 4 right angles and all sides equal in length.
- A rhombus has diagonals that are equal in length and bisect each other at right angles.
- A kite has diagonals that are unequal in length, with one diagonal bisecting the other at right angles.
- Squares, rhombuses, and rectangles are types of parallelograms.
- A trapezium has only one pair of parallel sides.
Data Collection Methods
- A teacher should use tests to assess student understanding.
- A gym owner should utilize opinion polls to determine popular exercise classes.
- Observation is suitable for studying people working in their natural environment without their knowledge.
- Questionnaires can gather data on the popularity of specific school clubs.
- To find people's favorite type of takeaway, a survey should be conducted using a questionnaire.
Sampling Methods
- Cluster sampling involves splitting the population into groups, then random selection of groups to survey all individuals within them.
- Quota sampling splits the population into groups and selects a fixed number from each group.
- Stratified sampling’s sample size is proportional to the population size.
- Random sampling employs methods like lotteries or random number generators to select individuals.
- Systematic sampling selects every nth individual from a list.
Circles
- The radius is the line length from the center to a point on the circle.
- The diameter is the line length passing through the center, connecting two points on the circle.
- The circumference is the distance around the circle.
- The formula for circumference is (C = 2\pi r).
- Pi ((\pi)) represents the ratio of a circle's circumference to its diameter.
Geometry Tasks
- For a rectangle, dimensions are required to identify specific attributes.
- To construct a line of length 8 cm, draw and bisect it accurately.
- Angles can be bisected using a protractor for precision.
3D Shapes and Polyhedrons
- A 3D shape with 3 faces, 0 vertices, and 2 edges is not a polyhedron as polyhedrons must have at least 4 faces and vertices.
Area and Volume Calculations
- Area of a parallelogram requires base and height measures.
- To find the height of a trapezium given its area, apply the area formula (Area = \frac{1}{2}(b1 + b2) \times height).
- The volume of a triangular prism is calculated by using the formula (Volume = Base Area \times height).
- Surface area of a cube is determined by the formula (Surface Area = 6a^2) where (a) is the length of a side.
General Problem Solving
- Each area or volume calculation can be resolved using specified geometric formulas, ensuring key values are accurately computed.
