Lesson 8-1 Solve Problems Involving Scale Drawings
Quick Review: In a scale drawing, the scale is a ratio that relates each drawing length to the actual length it represents.  To find unknown lengths, you can use the scale to write a proportion.

Use the same floor plan for questions 2 - 4. scale 1.25 inches = 2 feet

2

The width of the floor in the drawing is 10.0 inches. scale 1.25 inches = 2 feet
What is the width of the actual floor?

16.0 feet

6.25 feet

10.0 feet

2

The length of the floor in the drawing is 12.0 inches. scale 1.25 inches = 2 feet
What is the length of the actual floor?

7.5 feet

12.0 feet

19.2 feet

What is the approximate area of the actual floor?

307 ft2

120 ft2

46.875 ft2

Lesson 8-2 Draw Geometric Figuress
Quick Review: You can classify a quadrilateral as a trapezoid, a rectangle, a parallelogram, a square, a rhombus, or a kite based on its side lengths, side relationships, and angle measurements.

2

Match each shape to its image.

Dane used a ruler and a protractor to draw a rhombus with a side that is 4 cm in length and an angle that measures 110°. Choose the angle measure that is missing from the diagram.
In a rhombus the two opposite angles are equal to each other.
All of the angles in a rhombus add together to equal 360º.

Laura is asked to draw a quadrilateral with two opposite angles equal to 105º. What possible shapes could she draw?

square, rhombus

parallelogram, rhombus

parallelogram, square

Lesson 8-3 Draw Triangles with Given Conditions
Quick Review: When you are given certain conditions for a triangle, it may be possible ot draw one triangle, more than one triangle, or no triangle.

When given angle measurements of 25º, 65º, and 90º, it is

possilbe to draw only one triangle.

impossible to draw a triangle.

possible to draw more than one triangle.
