– Calculate the distance between two points
– Calculate the middle coordinates of a segment.
– Solve problems of geometry hovering on simple or complex figures (triangle, quadrangles, circles).
– Calculate lengths, angles, areas and volumes.
Activity 1: Using the following geogebra applets, the middle and length formulas of a segment should be obvious to you….
Length of a segment (use of pythagorean theorement in rectangle triangle)
Middle of a segment:
Exercise 9 Index: Use this geogebra applet to place the A’, B’, and C’…
For the calculation of EH, do not forget the relationship of Pythagoras … do the same to calculate the height of the CBF triangle from F…
