Triangle Artwork Project

Chapter 4: Congruent Triangles Project

Triangle Artwork                        Due Date: Thursday November 6^th 2014

Introduction:

For this project you will work individually creating an art project using nothing but triangles. You will create a piece of original artwork on a large piece of poster paper (one piece will be provided to the student) and you will be graded on the originality and neatness of the work.

Objective:

The objective of this project is to use what you know about congruent triangles and their construction, as learned in chapter 4, to create an original work of art.

Materials:

-          Geometry textbooks

-          large poster paper

-          rulers/straight edge

-          protractor

-          markers

-          crayons

-          pencils

-          colored pencils

Criteria:

Part 1 - Artwork (20 points):

You will be creating a piece of artwork using triangles and triangles only. NO other shapes are permitted in your project. If you want any other shapes, you must make them out of triangles. Be creative and colorful in your design using crayons, colored pencils or markers only (No paint or watercolor, of any kind can be used unless special permission is given)

Your design must include the following:

-          

                   acute triangles

-                              obtuse triangles

-                             right triangles

-                            scalene triangles

-                            equilateral/equiangular triangles

-                           isosceles triangles

You may use as little or as many of the above mentioned triangles in your artwork; however, each type of triangle must be used at least once and the entire poster board needs to be covered. No white of the poster board should be exposed and 90% of the poster board needs to be covered in triangles. You MUST us a ruler! Do not free hand the triangles.

Part 2 - Written Report (20 points):

In addition to your physical project you will also need to complete a written component to accompany the artwork. Your paper should be exactly 1 page in length and cover the following topics.

Paragraph 1: Introduction

Paragraph 2: Provide detailed explanations and descriptions of your artwork: explain how were you inspired to create your artwork, what inspired you to create your artwork, what does your artwork represent, etc.

Paragraph 3: Describe how you used the different types of triangles listed above along with an explanation of the process used in creating the image(s) in your artwork; how did you use different triangles to create your image.

Paragraph 4:  Provide your opinion of the project: how do you feel about your final product, did you enjoy the project, do you feel it reinforced what you learned in the chapter, etc.

Part 3 – Oral Presentation (10 points):

Each student, before submitting their project, will provide a brief (2-3 minute) summery of their artwork and the inspiration behind it. Students will be expected to present their ideas thoughtfully and speak clearly.

Presentation will take place in class Thursday (November 6^th) and Friday (November 7^th)

This project is worth 50 points

* Use your imagination and have fun with this project. Creativity and overall presentation will affect your grade.

* No late projects and written reports will be accepted. Use your time wisely in class. If you get behind, you must complete work on the project at home.
