In Chapter 8 we learned about multiple aspects of Geometry. Our Part 1 Review will cover:
Scale Drawings
Drawing Geometric Figures
Creating Triangles with Specific Dimensions
Determining Angle Relationships
Vocabulary Review: Complete each definition and then provide an example of each vocabulary word.
Use triangle ABC to help match some of the vocabulary terms.

Side AC, which is between Point A and Point C, can also be called ______________ AC. | arrow_right_alt | scale drawing |
____________ have a sum of 180º. | arrow_right_alt | included side |
Angle B is a(n) ___________ between sides AB and BC. | arrow_right_alt | supplementary angles |
Opposite and equal angles that area created by the intersection of two lines. | arrow_right_alt | included angle |
An enlarged or reduced drawing of an object that is proportional to the actual object. | arrow_right_alt | complementary angles |
____________ have a sum of 90º. | arrow_right_alt | vertical angles |
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.
On a scale drawing of a fence, 3.75 inches represent 24 feet. What is the actual length of a fence that is 2.8 inches long in the drawing?
On the floor plan shown below, 1.25 inches represents 2 feet. What is the actual area of the entire floor?
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.
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.
All of the angles in a quadrilateral add together to equal 360º.
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?
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
Explain your answer to question 8. How did you know the number of triangles you can create from the given angle measurements?
Quick Review:
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.
Find the value of x.
Determine the value of the smaller angle.
