Math

• A net of a shape is what a 3d shape would look like if it was laid out flat

  e.g.

  
• This is the net of a cube

  
• This is the net of a cuboid

  
• This is the net of a pyramid

  
• This is the net of a triangular based pyramid

  
• This is the net of a triangular prism

  
• What is the area of this shape

  answer: 12

  
• What is this part of the circle called?

  answer: arc

  
• What is this part of the circle called?

  answer: chord

  
• What is this part of the circle called?

  answer: radius

  
• What is this part of a circle called?

  answer: tangent

  
• What is this part of a circle called?

  answer: segment

  
• What is this part of a circle called?

  answer: diameter

  
• the difference between a chord and a segment is that the segment is usually shaded

  this is a segement a chorder would be unshaded:

  
• the cirfumference of a circle is the whole way around the circle

  the circumference is the red line here

  
• Alternate angles usually make a Z shape

  the Z shape of can also be backwards just like its shown in this diagram

  
• Vertically opposite angles are always opposite of each-other and have the same amount of degrees

  just like its shown in this diagram

  
• Corresponding angles make an F shape

  the F shape can be upside down and backwards

  here is an exapme
