### Day 2: Triangles with geogebra

You already know that we can classify the triangles acording to their angles and acording to their side lengths. Read this link if you want to know more.

### Activity

- Open geogebra and draw in the same canvas the following triangles:
- Equilateral triangle
- Isosceles triangle
- Scalene triangle
- Save the .ggb file
- Open another geogebra file and try to draw the following triangles:
- Acute triangle
- Obtuse triangle
- Right triangle
- Save the .ggb file
- Questions:
- Draw here a short definition for each kind of triangle according to their side lengths.
- In the second file, use then the angle utility of geogebra and measure each angle. How much is the sum of the 3 angles of a triangle?
- Send an email to the teacher with the two .ggb files attached and the answer to the questions.
