Intended Learning Outcomes

At the end of the lessons you can...

• Calculate a leg in a right-angled triangle
• Use and recognize Pythagoras's Theorem in contexts and situations
• Draw sketches and auxiliary lines to calculate sides with Pythagoras's Theorem

Remember:

Pythagoras ónly works in right-angled triangles

                                                      -->

AB = 6 and AC = 8.
Calculate BC.

1. BC=√​72​​​
2. BC=9
3. BC=10
4. BC=11

Two of the following
statements are true.
Which ones?

1. AC​2​​−BC​2​​=AB​2​​
2. AB​2​​−AC​2​​=BC​2​​
3. BC​2​​−AB​2​​=AC​2​​
4. BC​2​​−AC​2​​=AB​2​​

Calculating a leg

                                                      'Neat' way                                  Quicker way

Let's make it a bit harder...

Try to explain how you would
solve the exercise on the right.

Draw an auxiliary line!

What is the height of the house?

Draw auxiliary lines!

...and find right-angled triangles
