What is the Pythagoras Theorem?
The Pythagoras Theorem states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Understanding Right-Angled Triangles
A right-angled triangle has one angle measuring 90 degrees, which is called the right angle.

#### Slide 5 -Slide

Identifying the Hypotenuse
The hypotenuse is the side opposite the right angle in a right-angled triangle.

#### Slide 6 -Slide

Calculating the Hypotenuse
To calculate the hypotenuse, we can use the Pythagoras Theorem: c^2 = a^2 + b^2

Write down 3 things you learned in this lesson.

#### Slide 14 -Open question

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.
Write down 2 things you want to know more about.

#### Slide 15 -Open question

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

#### Slide 16 -Open question

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
