Many geometric shapes contain right angles and right-angled triangles.
You may find it helpful to sketch the right angled triangle being used.
Find a right angled trianngle out of a shape and use this example and theorem
xsq =5q +8sq
>xsq =25+64
>xsq =89
>x=89sqroute =9.4 (to 1 d.p)
*the sq is squared and sqroute is canna obvious but its square route
I [...]

At the start of the lesson our aiims were:
1. To become confident about using Pythagoras’s technique.
2. To Learn how to find the missing shorter side.
ok so u all saw sorrel’s amazing post on pythagoras’ theorem. i will just add a tiny bit more. Yesterday in maths mr jones taught us how to find [...]

 
We call C the Hypotenuse of this right angled triangle.
The Hypotenuse is allways opposite of the right angle!  This is the process to work out the length of C!
Using the length of A draw a square,(all the sides of the square are the same length). repeat this on the b and c sides of the triangle   :
 
Square A and B [...]
