• The area of a triangle can be calculated using the formula A = 1/2 * base * height.
• if the radies was 3 what would the area be

  pie x3 squared =9pie=28.3
• The circumference of a circle is the total length around it, while the diameter is twice the radius.
• to find the circumference of a circle you?

  pie x diameter
• to find Pythagoras theorem you do a2+b2=c2
• what is the hypotenuse

  the longest side in a triangle
• how do you find the hypotenuse

  square , add , square root
• how do you find the shorter side

  square , minus, square root
• • in a scalene triangle non of the sides are equal
• in a isoselce triangle 2 of the sides are the same
• if the radius of the circle is x then the diameter is x/2
• in a euqalatrial triangle all the sides are equal
• • to find a missing length in a right angle triangle you square both sides then add together then square root it
• when looking for a another side which is not the hypotenuse you square both then subtract then square root it
• to solve this you need to do 20 squared x pie =20pie=62.8cm2
• the opposite is the side opposite the angle used
