Angle Formulae
Rule 1: Angles around a point add up to 360°.
Rule 2: Angles on a straight line add up to 180°.
Rule 3: Angles in a triangle add up to 180°.
Rule 4: Angles in a quadrilateral add up to 360°.
Parallel Lines
Lines are parallel if they will never intersect.
Rule 1: Corresponding angles are equal - these are angles in a letter 'F'.
Rule 2: Alternate angles are equal - these are angles in a letter 'Z'.
Two lines are perpendicular if they meet at 90°.
Use a compass for the construction lines.
Usually we set the compass, clearly past half of the distance between A and B.
Cube: Volume = length x width x height
Cuboid: Volume = length x width x height
General 3D shape: Volume = area of 2D shape x height
The blue line is a diameter
The yellow line is a radii
The orange line is a chord
The green line is a tangent
The black line is the circumference
Mode: The MOde is the MOst common
Mean: The mean is the average of a set of numbers. To find this we add all the numbers together and divide by the total amount of numbers.
Median: To find the median, we first arrange the numbers in order then find the middle number.
Range: The biggest number – smallest number
