⁦Lines and planes in space⁩

⁦Use a cuboid to find how two lines can sit in space⁩: ⁦parallel, intersecting or skew⁩. ⁦Then look at a line and a plane, a line perpendicular to a plane, and the angle between two skew lines⁩.

⁦This studio follows Afghan Year 11 chapter 3 (space geometry) and Iran⁩'⁦s Year 10 geometry chapter 4⁩. ⁦In space two straight lines have three possibilities⁩: ⁦they are parallel, they meet at one point, or they are skew, which means they are neither parallel nor meeting because no single plane contains both⁩.

⁦Your child can turn the solid by dragging, with the arrow buttons or the arrow keys, and show the hidden edges⁩. ⁦Two lines that cross in the picture may have no point in common in space⁩.

⁦A line is perpendicular to a plane if it is perpendicular to two intersecting lines of that plane; it is then perpendicular to every line of the plane⁩. ⁦The angle between two skew lines is measured with a line parallel to one of them drawn through a point of the other⁩.
