16 kwi 2024 · A scale drawing of an object is the same shape at the object but a different size. The scale of a drawing is a comparison of the length used on a drawing to the length it represents. The scale is written as a ratio. The ratio of two corresponding sides in similar figures is called the scale factor.
The scale 1 : 20 means that one centimetre on the scale drawing represents 20 cm in real life. The drawn length multiplied by 20 gives the real length.
A scale drawing is a scaled representation of an object. The scale tells us how lengths on the drawing relate to lengths on the actual object. For example, in the basketball court activity, we saw that 1 centimeter on the drawing represented 2 meters of actual distance on the actual court.
SHAPES Scales, which are similar to rulers, come in several shapes. The various shapes allow for a different number of scale ratios to be used. An opposite bevel scale has two sides with only one scale ratio on each side. A two-bevel scale also has two scale ratios, but they are on the same side.
The scale of a drawing is usually stated as a ratio. For example, 1 \, cm \, \text{:} \, 5 \, m. You would read this as “ 1 centimeter to 5 meters” which means that every 1 centimeter on the diagram represents 5 meters in real life.
15 sie 2020 · Suppose we want to make another scale drawing of the park where the scale is 1 cm to 30 meters. This new scale drawing should be 30 cm by 12 cm, because \(900\div 30=30\) and \(360\div 30=12\). Another way to find this answer is to think about how the two different scales are related to each other.
The scale ruler comes in different shapes, flat or triangular but they all provide sets of graduated numbered spaces, which establishes a proportion of one unit to the specified unit, i.e. different scales. As an example, the ruler I have in front of me now has the following scales: 1:1, 1:100, 1:20, 1:200, 1:5, 1:500, 1:1250, 1:2500.
