a popular tourist attraction in ottawa is the Peace tower, which rises from the Center Block of the Parliment buildings. Describe at least one method that you could use to estimate the height of the tower, including the measurments you would need to make. Include labelled diagram, explination of similar triangles, and the proportion you would use
Measure the length of the shadow of the tower.
Measure your own height
set up the ratio:
height of peace tower/lenght of its shadow = your height/length of your shadow,
You have 3 out of the 4 numbers, cross-multiply and solve for the height of the peace tower.
BTW, having been on Parliament Hill many times, I know for a fact that this will not work, since the grounds of the "hill" are not level, so your angles of the two triangles will not be the same, thus you have no similar triangles.
The above method assumes that the ground would have a uniform slope throughout.
To estimate the height of the Peace Tower in Ottawa, one method that can be used is by utilizing similar triangles. We can compare the known height and length of an object in our line of sight with the corresponding height and length of the tower. Here's a step-by-step explanation of this method:
Step 1: Find a suitable line of sight: Position yourself at a certain distance from the Peace Tower where you can clearly see the entire height of the tower.
Step 2: Measure the distance from your line of sight to the base of the Peace Tower: Use a measuring tape or any other appropriate measuring tool to determine the length from your position to the base of the tower.
Step 3: Choose a reference object of known height: Identify an object nearby whose height you know. It could be a building, a signpost, or any other object with a known height.
Step 4: Measure the actual height and distance of the reference object: Use the same measuring tool to determine the actual height and distance from your line of sight to the known-height reference object.
Step 5: Set up the proportion: Create a proportion using the height and distance measurements of both the reference object and the Peace Tower. Label the measurements as follows:
- Reference object's height: h1
- Distance to the reference object: d1
- Peace Tower's height (unknown): h2
- Distance to the Peace Tower (measured in Step 2): d2
Write the proportion as follows:
h1 / d1 = h2 / d2
Step 6: Solve the proportion: Substitute the values measured in Steps 3 and 4 into the proportion and solve for h2.
Step 7: Calculate the estimated height of the Peace Tower: Using the solved value for h2, you can determine the estimated height of the Peace Tower.
To visualize this method, refer to the labelled diagram below:
```
A o------------------------o B
/| |\
/ | | \
/ d1 | \
/ | | \
/ | h1 Ans | \
/ | | \
(Reference Object) (Peace Tower)
```
In this diagram, A represents your position, B represents the base of the Peace Tower, d1 is the distance to the reference object, h1 is the height of the reference object, and Ans is the estimated height of the Peace Tower (h2). The measurement d2 is the distance from your position to the base of the Peace Tower, which needs to be determined in Step 2.
The method of similar triangles relies on the fact that corresponding angles between two triangles are equal, so the ratios of corresponding sides are also equal.
To estimate the height of the Peace Tower in Ottawa, we can use a method called the "similar triangles." This method involves using the properties of similar triangles to determine the unknown height.
Here is a step-by-step guide on how to estimate the height of the Peace Tower:
1. Find a location in Ottawa where you have a clear view of the Peace Tower, preferably from a distance. This will ensure that we can see the entire tower and have a good perspective.
2. Set up a measuring tape or rulers horizontally at the ground level. Make sure the tape is parallel to the ground and perfectly level. Label this as Line AB.
A ---------- B
3. Measure the distance from Line AB to your viewing location. Let's call this distance 'd'. Make sure to measure it in the same units as the height of the Peace Tower will be measured (e.g., meters or feet).
A ---------- B

4. Find a vertical object near Line AB that you can measure. It can be a lamppost, a building, or any other object whose height you know. Measure the height of this object and label it as 'h'.
5. Observe the Peace Tower and identify a point on the tower directly below the top, where you choose to measure the height from. Label this point as 'C'.
6. Now, align two points vertically on the measuring tape or ruler at Line AB. One point should be at the bottom of the vertical object (point A), and the other point should be at the top of the object (point B).
7. Look through the measuring tape or ruler, aligning your view so that point C on the tower aligns with point B on Line AB.
8. Adjust the measuring tape or ruler vertically until it aligns with the top of the Peace Tower (point C). Take note of the measurement where the measuring tape or ruler aligns with point A.
9. Let's label the height of the Peace Tower as 'H'.
A ---------- B

10. Now we have two similar triangles: triangle ABC and triangle A'C'B'. Triangle ABC is the actual triangle formed by the Peace Tower, Line AB, and the measuring tape/ruler. Triangle A'C'B' is the replica of triangle ABC formed on the measuring tape/ruler.
11. By the properties of similar triangles, we can write the following proportion:
(h / d) = (H / x),
where h is the known height of the object, d is the known distance from Line AB to your viewing location, H is the unknown height of the Peace Tower, and x is the measurement on the ruler when the measuring tape is aligned with the Peace Tower.
12. Rearrange the proportion to solve for the height of the Peace Tower (H):
H = (h * x) / d.
Now you can use this formula to calculate the estimated height of the Peace Tower based on the measurements you have made. Remember, accuracy depends on the precision of your measurements, so ensure accurate measurements for the best estimate.
