Lesson 7: Scale Drawings

Math 7

Multiple Choice

What is a scaled drawing?

• a scaled representation of an object

• a non-scaled representation of an object

Multiple Choice

How can we describe the scale for a scale drawing?

• The scale tells us how lengths on the drawing relate to lengths on a different drawing.

• The scale tells us how lengths on the drawing relate to lengths on the actual object.

Multiple Choice

How do we find distances using a scale drawing?

• If we have a scale drawing, we can use addition to find lengths on the actual object.

• If we have a scale drawing, we can use the scale to find lengths on the actual object.

• If we have a scale drawing, we can use subtraction to find lengths on the actual object.

• If we have a scale drawing, we can use the protactor to find lengths on the actual object.

1 centimeter on the drawing represented 2 meters of actual distance on the actual court.

It is important to remember that a scale drawing shows scaled measurements in only _ dimensions

Multiple Choice

Measurements of a particular surface of an object and those that have been projected onto a particular plane.

• two dimensional (2D) measurements

• three dimensional (3D) measurements

Fill in the Blanks

A _ represents an actual place or object. All the measurements in the drawing correspond to the measurements of the actual object by the same scale.

Fill in the Blanks

_ tells how the measurements in a scale drawing represent the actual measurements of the object

A scale drawing of a scooter has a scale of  $$\frac{1}{2}$$   inch to 5 feet. If the length of the sooter is $$5\frac{1}{2}$$  on the scale drawing, what is the actual length of the bus? Explain or show your reasoning.

Fill in the Blanks

The actual length of the bus is _.

Fill in the Blanks

The width of the lake on the scale drawing is _.
