Summary

This video provides a step-by-step guide on how to estimate the height of a tree using the triangle comparison method. The presenter demonstrates the process using a tree, a friend with a stick, and a clear set of instructions, emphasizing that this method is only suitable for flat ground. After measuring distances and setting up the right angles, the height is calculated using basic math principles. The video concludes with a reminder to like, share, and subscribe while apologizing for any errors in the steps, and thanking viewers for watching.

Takeaways

• 😀 The video is about teaching how to estimate the height of a tree using the triangle comparison method.
• 😀 This method works best in flat areas where the surface is level.
• 😀 The video demonstrates the method using a tree and a friend as an assistant.
• 😀 A scout's stick, which is 160 cm long, is used for measurement in the process.
• 😀 The distance from the tree (point A) to the friend (point B) is measured in terms of scout sticks, totaling 7 sticks (1120 cm).
• 😀 The friend sets up a stick at point B, and another scout is tasked with lining up the top of the tree and the stick's top.
• 😀 The distance between the stick and the observer (point C) is also measured in scout sticks, totaling 2 sticks (320 cm).
• 😀 To calculate the tree's height (A-E), a formula is used: AE = (AC ÷ BC) × AB.
• 😀 The values used in the formula are AC = 1440 cm, BC = 320 cm, and AB = 160 cm.
• 😀 After calculating, the tree's height is determined to be 7.2 meters (720 cm).
• 😀 The method is simple but effective, and the video encourages viewers to like, share, comment, and subscribe for more content.

Q & A

What method is being used to estimate the height of the tree in this video?

The method used to estimate the height of the tree is the 'triangle comparison method' or 'similar triangles method'.

What is the main limitation of the triangle comparison method?

The main limitation of the triangle comparison method is that it can only be performed on flat terrain.

What object is used in the process to estimate the tree's height?

A standard 160 cm long scouting stick (tongkat pramuka) is used in the process.

How is the distance between point A (the tree) and point B measured?

The distance between point A (the tree) and point B is measured by having a friend walk away from the tree, and the distance is calculated in multiples of the standard 160 cm scouting stick.

How is the distance between the stick and the peak of the tree measured?

The distance between the stick and the peak of the tree is measured by having a friend sight along the stick and the tree top, and this distance is also expressed in multiples of the scouting stick.

What formula is used to calculate the height of the tree?

The formula used to calculate the height of the tree is: height of tree (AE) = (AC / BC) * CD, where AC is the total distance from A to C, BC is the distance from the stick to the observer, and CD is the length of the scouting stick.

How do you calculate the total distance AC in the formula?

The total distance AC is the sum of the distance AB (7 sticks) and the distance BC (2 sticks), giving AC = 1440 cm.

What does 'BC' represent in the formula?

'BC' represents the distance from the base of the stick to the observer, which in the example is 320 cm (2 sticks).

What was the final height of the tree calculated to be?

The final height of the tree was calculated to be 7.2 meters.

Why is it important to ensure that the terrain is flat when using this method?

It is important for the terrain to be flat because the triangle comparison method assumes a level ground to ensure accurate proportional comparisons between distances.
