Day 75: Scale Drawings & Similar Figures

Front

What is a scale drawing?

Back

A scale drawing is a representation of an object or space that maintains the proportions of the original, using a specific ratio to reduce or enlarge its size.

Front

What does 'similar figures' mean?

Back

Similar figures are shapes that have the same shape but may differ in size. Their corresponding angles are equal, and their sides are in proportion.

Front

How do you calculate the actual length from a scale drawing?

Back

To find the actual length, multiply the length in the scale drawing by the scale factor.

Front

If a scale is 1 cm : 5 m, what does this mean?

Back

This means that 1 cm on the drawing represents 5 meters in reality.

Front

What is the formula to find the scale factor?

Back

Scale Factor = Actual Length / Drawing Length.

Front

How do you convert measurements from one unit to another?

Back

To convert measurements, use conversion factors that relate the two units (e.g., 1 inch = 2.54 cm).

Front

If a model is built at a scale of 1:10, what does this indicate?

Back

This indicates that every 1 unit of measurement on the model represents 10 units in real life.

Front

What is the actual height of a structure if a 2 ft model is built at a scale of 3 in : 78.75 ft?

Back

The actual height is 630 ft.

Front

How do you find the dimensions of a house from a scale drawing of 9cm x 10cm with a scale of 6cm = 12ft?

Back

The actual dimensions are 18ft x 20ft.

Front

What is the diameter of a model if the actual diameter of an artery is 2.7 mm and the scale is 2.5 cm : 0.75 mm?

Back

The diameter on the model is 9 cm.
