TRIANGLES

Proofs of the following theorems are deleted:

• If a perpendicular is drawn from the vertex of the right angle of a right triangle to the hypotenuse, the triangles on each side of the perpendicular are similar to the whole triangle and to each other.
• The ratio of the areas of two similar triangles is equal to the ratio of the squares of their corresponding sides.
• In a right triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides.
• In a triangle, if the square on one side is equal to sum of the squares on the other two sides, the angles opposite to the first side is a right angle.
