Using a scale of 1cm to represent 5m or 1:500,measure the sides and angle:right angle triangle,right angle and scalene
To measure the sides and angle of a right angle triangle with a scale of 1cm to represent 5m or 1:500, you can follow these steps:
1. Label the vertices of the right angle triangle as A, B, and C, where C represents the right angle.
2. Determine the length of the two legs of the triangle. Let's assume that the length of side AB is 10m and the length of side BC is 24m.
- Using the scale, convert the length of AB to the corresponding length on the diagram:
Length of AB on the diagram = (Length of AB in m) / (Scale factor)
= 10m / 5m
= 2cm
- Similarly, convert the length of BC to the corresponding length on the diagram:
Length of BC on the diagram = (Length of BC in m) / (Scale factor)
= 24m / 5m
= 4.8cm
3. Measure the length of side AB on the diagram using a ruler. If 1cm on the diagram represents 5m, and the length of AB on the diagram is 2cm, then the actual length of AB would be:
Length of AB in m = (Length on the diagram) * (Scale factor)
= 2cm * 5m
= 10m
4. Measure the length of side BC on the diagram using a ruler. If 1cm on the diagram represents 5m, and the length of BC on the diagram is 4.8cm, then the actual length of BC would be:
Length of BC in m = (Length on the diagram) * (Scale factor)
= 4.8cm * 5m
= 24m
5. To measure the right angle, use a protractor to determine the angle at C. Place the protractor with its center at the vertex C and align one arm of the protractor with side AC. Read the angle measurement from the protractor.
Note: The measurements provided in steps 3 and 4 are based on the assumption of the lengths of sides AB and BC mentioned earlier. You will need to adjust the calculations and measurements based on the specific values of your right angle triangle.
