interior angles 💙

• how to work out interior angles

  360 •\• amount of sides of shape = ans

  
  

  180 - ans = x
• question - one interior angle is _ , workout how many sides this shape has

  
  

  1. work out exterior angle = 180 - __ = answer
  2. do 360. •\• answer = x
  3. x is the final answer of sides
• tesselation - how many shapes can fit into another
• if don’t know sum of interior angles in total a shape has, focus on 1 point of a shape, then draw triangles coming off it (triangles 180•), then do 180 x the amount of shapes you could fit in, done
