iGeom
The next exercises are used to introduce the Interactive Geometry
with iGeom. They are designed to present the basic question: the objects must reflect the dependence.
For instance, if you want to construct a segment initiating in an intersection point of 2 circles,
you must select the correct one, since (usually) there are 2 of them.

|
Exercise 1 |
Given the points A, B and C and the circle c0, you must construct:
the mesaure of the arc BAC, the radius of c0 (distance |A-B|), then, using
the interactive calculator, you must define the fraction arc BAC/distance |A-B|.
|
|
Exercise 2 |
Given the points A, B and C and the radius r and s, you must construct:
the bisection of these 2 rays (another ray that is equidistant of both).
|
|
Exercise 3 |
Given the points A and B, you must construct the midpoint of AB.
|
|
Exercise 4 |
Given the points A and B, you must construct the perpendicular line of AB
(i.e., the line that is perpendicular to AB and pass by their midpoint).
|
|
Exercise 5 |
Given the points A and B and the segment r, you must construct a square over AB.
Note that there are 2 possibilities, you must produce the one whose vertex are above AB, when considering.
the initial configuration.
|
|
Exercise 6 |
Given the points A and B, you must construct a equilateral triangle over AB.
Note that there are 2 possibilities, you must produce the one whose vertex are above AB, when considering.
the initial configuration.

Remember:
- iGeom do not use the "drag-and-drop" pattern, in order to reduce
stress-related muscle tension, reducing harm with the intensive use of the software.
So, usually you need to click the construction button, them click the drawing area (or some object).
- After you finish you exercise answer, please, click the button
