Unit III: Geometry
1. Triangles
- Definitions, examples, counter examples of similar triangles
- (Prove) If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio
- (Motivate) If a line divides two sides of a triangle in the same ratio, the line is parallel to the third side
- (Motivate) If in two triangles, the corresponding angles are equal, their corresponding sides are proportional and the triangles are similar
- (Motivate) If the corresponding sides of two triangles are proportional, their corresponding angles are equal and the two triangles are similar
- (Motivate) If one angle of a triangle is equal to one angle of another triangle and the sides including these angles are proportional, the two triangles are similar
- (Motivate) 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
- (Prove) The ratio of the areas of two similar triangles is equal to the ratio of the squares on their corresponding sides
- (Prove) In a right triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides
- (Prove) 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 triangle
