Area of a triangle

Triangles

Proof of the following theorems are deleted:

The triangles on either side of a perpendicular are identical to the triangle as a whole and to one another when the perpendicular is traced from the vertex of a right triangle to the hypotenuse.

The ratio of the squares of the identical sides of two comparable triangles equals the ratio of their areas.

The square on the hypotenuse of a right triangle equals the sum of the squares on the other two sides.

The angle opposite the first side of a triangle is a right angle if the square on one side equals the sum of the squares on the other two sides.

Internal Assessment (Periodic Tests, Portfolio, Lab Activities, etc.)

Periodic Examinations: There are three exams offered all year long, each worth ten points. The ultimate mark submission will be based on the average of the top two tests.

A portfolio is a compilation of a student's mathematical accomplishments, including worksheets, projects, and assignments. It is worth five marks.

Lab Activities: Five-point assignments consisting of students' hands-on work in the mathematics lab, including experiments, models, charts, etc.
