Watch this presentation about the remarkable points and straight lines in a triangle, and then watch the tutorials.
You have to see them in this order:
1)Circumcenter
2) Incenter
3) Barycenter
In the three remaining boxes you have to do:
We are going to build triangles from some information about their shape. First of all, do a margin on your sheet and divide it into 6 equal parts 0.
Dividing a sheet into 6 equal parts (optional)
Before starting, you have to see the presentation about the triangles and then see the 3 tutorials in this order:
1. Triangles 1: Contruction of a triangle knowing 2 sides and one angle
2. Triangles 2: Contruction of a triangle knowing 2 angles and one side
3. Triangles 3: Contruction of a triangle knowing 3 sides
You have to do these 3 activities:
1. Draw one triangle knowing 2 sides and one angle: AB=8cm; AC=6,5cm and A=30º
2. Draw one triangle knowing 2 angles and one side: AB=7cm; A=30º and B=60º
3. Draw one triangle knowing 3 sides and one angle: AB=7,5cm; AC=4cm and BC=7cm
