⭐ The video discusses the application of the Thales' theorem.
🔍 It explains how to determine the value of 'x' in a given figure.
✏️ The use of parallel lines and intersecting segments is essential in solving the problem.
🔑 In the given exercise, we are dealing with a proportion involving three known values and one unknown value.
📐 To solve for the unknown value, we can use the method of cross-multiplication and obtain an equation without fractions.
⚖️ By cross-multiplying, we find that 9 times the unknown value is equal to 144, allowing us to solve for the value of x.
🔑 The video is about using the Theorem of Thales to solve a geometric problem.
📐 The Theorem of Thales states that if three parallel lines intersect two transversals, then the ratios of their corresponding segments are equal.
💡 In the given problem, we can't directly apply the Theorem of Thales, but we can use the corresponding angles formed by the parallel lines to find the value of x.
The exercise involves finding an angle at a vertex formed by intersecting lines.
The angle at the vertex is equal to the angle in the triangle ABC.
Using the similarity criterion of three angles, the small triangle ade is similar to the larger triangle abc.
🔑 The video explains the concept of the Theorem of Thales and its applications in triangles.
📐 It emphasizes the importance of identifying and labeling the interior angles of triangles.
✖️ The video demonstrates how to solve for the unknown length of a side using the Theorem of Thales and proportions.
🔑 In the video, we learn about the Teorema de Tales and solve a specific exercise.
🔢 To solve the exercise, we use multiplication and divide to find the value of x.
✏️ The final answer is x = 35.
