EMILE : Enseignement d'une Matière Intégrée à une Langue Étrangère

### Activity #1 Here are 4 steps of construction of a specific figure. It's like a stop motion movie. Each numbered step matches with one instruction. What is the first one? Ο    Trace a triangle rectangle named ABC. Ο    Trace a right triangle named ABC. What is the next one? Ο   Trace the circle of center B going through point A. Place point I at intersection of BC and this circle. Ο   Trace the circle whose radius is AI. What is the third one? Ο   Draw the parallel line to AB. Ο    Draw the perpendicular line to AC passing by I. What is the last one? Ο    The parallel to AB going through I intersects AC at point J. Place J. Ο    This perpendicular line goes through point J. Find J. Now, it is up to you to imagine instructions in order to get the number-4 figure. What would be the first one? What segment has been added in step 2? Point E is at intersection of which lines? In step #4, how is line EF with respect to line DC?

### Activity #2

 We are going to draw a geometrical figure, step by step. You have to find which instruction is given to see the blue object Step 1 O    Trace a line. O    Trace a square.  Step 2 O    Trace a point. O     Trace a point C. Step 3 O     Trace a circle cutting the line in 2 points. O     Trace a circle going throuhg point C. O     Trace a circle whose radius is C. O     Trace a circle whose center is C. It must intersect the line at two points.  Step 4 O     Name D and E the intersection points of circle and line. O     Place D and E. Step 5 O     Trace circle whose center is C and radius CD. O     Trace circle whose center is D and radius CD.  Step 6 O     Trace circle whose radius is CE and center C. O     Trace circle of center E and radius EC. Step 7 O     Place F. O     Place F at intersection of two circles. O     Place F as symmetrical of C with respect to line.  Step 8 It's up to you to write the next instruction. Step 9 I took my square set and check that... O     line CF is perpendicular at the first line. O     line CF is perpendicular to the first line. O     line CF is perpendicular on the first line.  Step 10 Finally, what can we do from one point, and one line, and all these steps. Lun-07-20 524.49 KB 400
