If you also join us at http://www.unicoos.com, it'll be great. #seeyouinclass :-) Corresponding to 3rd year of SECONDARY SCHOOL and related to SIMILARITY OF TRIANGLES, we will demonstrate that the similarity ratio "r" of two similar triangles also serves to relate their perimeters (r = P/P') and their areas (r² = S/S'). To find the perimeter of both triangles (in this case, right triangles), we will use the Pythagorean theorem since we do not know the value of the hypotenuse. In addition, I will solve two practical cases in which we will find the area and perimeter of a triangle, given the perimeter and area of another similar triangle and the ratio of their similarities. CLARIFICATION: Minute 9:54 The solution obtained is incorrect, as it would not fulfill the Pythagorean Theorem. Furthermore, one side of a triangle can never be greater than the sum of the other two. That's what happens when I make up examples on the fly...
