## 1.2. How to make a 3D shape into a net.

## 1.3. How to make a net into a 3D shape.

## 1.4. Features of a basic 3D shape

### 1.4.1. That the number of faces + the number of Vertics - 2 = the number of edges.

# 2. Nets

## 2.1. How to make a 3D shape into a net.

## 2.2. That a net is what you cut out and then fold the sides to make it into a 3D shape.

## 2.3. How to make a net into a 3D shape.

# 3. Translations

## 3.1. How to move a shape from one place to another.

### 3.1.1. To do this you need to figure out which was it goes horizontal like for example if it went left 2 and down 5 you would put it as '-2,-5'

# 4. Tessellations

## 4.3. That a regular polygon with more than 6 sides can't tessellate.

## 4.4. That only shapes that add up to 360 degrees when put together can tessellate properly.

## 5.1. That an angle of a square is 90 degrees.

## 5.2. That an angle of a triangle is 60 degrees.

## 5.3. That an angle of a hexagon is 120 degrees.

## 5.4. How to identify and name angles

# 6. Triangles

## 6.1. How to find the angle in a triangle.

## 6.2. How to accurately construct a triangle using a protractor and a ruler.
