What is an interior angle? Give as much info as possible
An angle inside a shape at a corner
What is the sum of exterior angles in a Polygon?
180 degrees
What is true for an Equation?
Needs to have an equals sign
Both sides must be balanced
What is the difference between an Inequality and an Equation?
Equations show that something is equal whereas inequalities compare two amounts

What is the formula to find the sum of the degrees in a Polygon?
(n-2) x 180
What is the sum of one interior and exterior angle and give a reason as to how you know?
180 degrees as it is on a straight line
Solve 2x = 18
x = 9
What is the difference between an open circle and a closed circle when showing an inequality on a number line?
An open circle relates to greater or less than
A closed circle includes equal to as well as being greater or less than
What is the 0th term in the sequence 8, 12, 16, 20...
4
What is the total degrees inside a Hexagon- You must say your working
(6-2) x 180 = 720 degrees
BONUS WHEEL
What is the size of one exterior angle in a Pentagon. Explain your working out
360 divided by 5 = 72 degrees
Solve 3x + 2 = 29
-2) 3x = 27
divide by 3) x = 9
If an inequality is x > 4 What is the first 3 Prime numbers that satisfies this?
5, 7 and 11
What is the gradient of a line with coordinates
(2,4) and (4,8)
Gradient = change in y divided by change in x
4 / 2 = 2
If two of the interior angles of a triangle are a right angle and 50 degrees. What is the size of the missing angle?
40 degrees
If the exterior angles in a Regular Polygon are 40 degrees each. Name the Polygon
360 divided by 40 = 9 so it is a Nonagon (9- sided shape)
Solve 3 (x + 2) + 5x = 54
Expand) 3x + 6 + 5x = 54
Simplify) 8x + 6 = 54
-6) 8x = 48
divide by 8) x = 6
If an inequality is x < 24 What are the possible factors of 24 which satisfy this?
1, 2, 3, 4, 6, 8, 12
BONUS WHEEL
What is 32% of 50?
You can swap the amounts around and do 50% of 32 which equals 16
What is the size of each interior angle in a regular Octagon?
135 degrees
BONUS WHEEL
The exterior angles of an irregular Polygon are 40, 80, 65, 45 and x.
What is the name of the Polygon and what is the size of the missing angle?
Pentagon and missing angle is 130 degrees (sum to 360)
Solve 2x + 5 = 4x - 3
x = 4 or 4 = x
Solve the inequality 4x - 12 > 36
+ 12) 4x > 48
divide by 12) x > 12
Factorise 12a + 30ab
HCF = 6a
6a (2 + 5b)
