Thale's Theorem

Our theme in this unit is Thale's Theorem.
The objectives of this unit are:
1) To calculate the lengths of segments by applying Thale's Theorem.
2) To prove that two lines are parallel by applying converse of Thale's Theorem.
3) To apply the property of the centroid in a triangle
4) To prove that a point represents the centroid of a triangle by applying the converse theoem of centroid.
5) To divide a segment into n equal parts.
6) To locate a point on a segment or a ray that divides the segment / ray in a given ratio.
7) To enlarge or reduce a geometric figure given a center and a scale factor.
8) To write the program of constuction.
9) To find the locus of a variable point with respect to fixed elements.

For the week of Jan. 23-Jan 27, we will cover the first eight objectives.
For the week of Jan.30 -Feb. 6, we will discuss the ninth objective.
