11. Lines and planes in three dimensions

(2 weeks)

:11.1 understand and use the concept of angle between lines and planes to solve problems.

(i) identify planes

(ii) identify horizontal planes, vertical planes and inclined planes;

(iii) sketch a three dimensional shape and identify the specific planes;

(iv) identify:

a. lines that lies on a plane;

b. lines that intersect with a plane;

(v) 5.identify normals to a

(vi) given plane;

(vii)determine the orthogonal projection of a line on a plane;

(viii) draw and name the orthogonal projection of a line on a plane;

(ix) determine the angle between a line and a plane;

(x) solve problems involving the angle between a line and a

Carry out activities using daily situation and 3-dimensional models.

Differentiate between 2-dimensional and 3-dimensional shapes. Involve planes found in natural surroundings.

Begin with 3-dimensional models.

Use 3-dimensional models to give clearer pictures.

11.2.understand and use the concept of angle between two planes to solve problems.

(i) 1.identify the line of intersection between two planes;

(ii) 2.draw a line on each plane which is perpendicular to the line of intersection of the two planes at a point on the line of intersection;

(iii) 3.determine the angle between two planes on a model and a given diagram;

(iv) solve problems involving lines and planes in 3-dimensional shapes.

Use 3-dimensional models to give clearer pictures.
