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?

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?

1

What is the approximate area of the actual floor?

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.

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.

2

A playground has two sides that each measure 70 feet and two sides that each measure 50 feet. Name the quadrilaterals that describe the shape of a playground with these dimensions. Select all that apply.

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

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.

1

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

2

Explain your answer to question 8.
Use the Similar versus Unique Triangles image to help support your answer.

8-4 Solve Problems Using Angle Relationships

Quick Review:

2

Examine the image. Use clues from the image as well as your angle types and relationships to answer each question.
Name a pair of vertical angles.
