Maths Paper 1
- Inequalities
- Example Question:
- We would show this on a number line like this
- We can see here that the point at 5 is shaded in because when we look back to the inequality we see that this sign is shown
- This means that 'n' is less than or equal to 5 so we show this by shading the dot above the 5 on the number line in.
- This means that 'n' is less than or equal to 5 so we show this by shading the dot above the 5 on the number line in.

- Solving in equalities
- Example question:
- First we need to subtract 3
from 11 which gives us 8. We
now know that 2x is less than
or equal to 8. 8 divided by 2 = 4.
Therefore 'x' is less than or
equal to 4.,

- Example question:
- Example Question:
- Angles in parallel lines
- Vertically opposite angles are EQUAL
- Corresponding angles are EQUAL
- Alternative angles are EQUAL
- Co-Interior angles add up to 180 degrees
- Vertically opposite angles are EQUAL
- Box plots
- Example Question:
- To do this we need to find 3 things:
- We then need to work out what they are
- Then draw out the box plot
- Then draw out the box plot
- We then need to work out what they are
- To do this we need to find 3 things:
- Example Question:
- Interior angles
- Finding the interior angle
- sum of interior angles = (n - 2) x 180
- 'n' means: number of sides
- 'n' means: number of sides
- sum of interior angles = (n - 2) x 180
- Example Question:
- Find the interior angle of a regular hexagon
- to do this we would need to do the sum of interior angles
divided by number of sides
- 720 divided by 6 = 120
- Therefore the answer is 120 degrees.
- Therefore the answer is 120 degrees.
- 720 divided by 6 = 120
- to do this we would need to do the sum of interior angles
divided by number of sides
- Find the interior angle of a regular hexagon
- Finding the interior angle
- Similar shapes
- To find the scale factor of 2 shapes you need to do the length of
a side on one shape divided by the length of the corresponding
side on the other shape.
- To find the scale factor of 2 shapes you need to do the length of
a side on one shape divided by the length of the corresponding
side on the other shape.
- Plotting a reciprocal graph
- Graphs of 'y' = 1/x, 2/x, 3/x
etc. are known as
reciprocal graphs and they
all have a similar shape
- Graphs of 'y' = 1/x, 2/x, 3/x
etc. are known as
reciprocal graphs and they
all have a similar shape
