So, ADBD=AECE ^ (using Thales Theorem) Then, 69 = 8x| = ^ 6x = 72 cm x = 72/6 cm x = 12 cm Hence, AC = 12+ 8 = 20. Thales’ theorem - LeWebPédagogique Instructor Anna Maria Choufany . EXERCISES 1. By using Thales Theorem, [As DE ∥ BC] AD/BD = AE/CE Then, 4/5 = AE/2.5 ∴ AE = 4 × 2.55 = 2 cm ix) If AD = x cm, DB = x - 2 cm, AE = x + 2 cm, and EC = x - 1 cm, find the value of x. We created another triangle by … Dante's Paradiso (canto 13, lines 101–102) refers to Thales's theorem in the course of a speech.

With the height of my hand, 15 cm, I can hide a 400-meter-high mountain standing far away. With Thales’ theorem, you must start with the circle, and then create a right angle. 3.2 Third similarity criterion Two triangles ABC and A’B’C’ are similar if Aˆ = Aˆ ' and c' c b' b = , this is like that because these triangles could be put in the Thales position on the vertex A. The Theorem of Thales: A Study of the Naming of Theorems … The Tales theorem says that if A, B, C are points on a circle, where AC is the diameter of the circle, then the angle ABC is the right angle. Mark on your paper the location of the corner of the colored index card and label this as point C. (make sure the sides of the index card are always touching A and B) c. Take the colored index card provided and push the card between points A and B pictured below: b. gwedynn Exercise 1 : Imagine a circle road, we have a town A far 13 km from town B, both are on the road, and it’s the maximum distance two town can have on this road.
