Indirect Mesurement

In this lesson, we explore the practical application of similar triangles to indirectly measure heights in real-world scenarios. Ramon uses a mirror placed on the ground to find the height of a geyser by walking back until he sees the geyser's top reflected in the mirror. Similarly, we analyze a cactus that casts a shadow and relate it to a person's height casting a smaller shadow to determine the cactus's height. This approach demonstrates the relevance of geometry in everyday life and enhances understanding of proportion and measurement.

  2. Real World Connection Ramon places a mirror on the ground and walks back until he can see the top of the geyser in the middle of the mirror. Use similar triangles to find the height of the geyser.

  3. Similar Triangles In sunlight, a cactus casts a 9-ft shadow. At the same time, a 6-ft person casts a 4-ft shadow. Use similar triangles to find the height of the cactus.

  4. Ramon places a mirror on the ground and walks back until he can see the top of the geyser in the middle of the mirror. Use similar triangles to find the height of the geyser.
