Unit Circle Explorer

Dear Year 8, Below is a program to help you look for relationships between sine, hypotenuse and opposite side of a right angled triangle.
  • Please use the slider to change the length of the hypotenuse
  • If you want to change the angle of your triangle, move the circle "B"
  • Look carefully at the black writing with "sine, hypotenuse and opposite" to try and spot the link. What mathematics can you find here?
  • Answer the questions in your book.
