1.In an artistic design by a contractor of the students' centre in a university, four pillars were erected to form two triangular figures with the vertices at first floor of the building and two of the pillars crossing each other. Proof that the spaces occupied by these two triangular figures are equal. 2. A kite is attarch to the ground at point A. On a level with A and in the same straight line the point B and C were chosen so that BC equals 100m. From the point B and C the elevation of the kite is 40° and 30° respectively. Find the distance between the point A and the kite. 3. Draw a diagonal scale 20mm:1m up to 8m and indicate 6.74m.
