1. Modern Geometry in Ancient Hawaiian Architecture Mrs. Place Intro Basic Geometry Class Kekoa High School Spring 2011

2. Project Objectives • Learn about ancient Hawaiian architecture • Utilize digital tools to consult on and showcase final project • Apply Geometric terminology toward a basic structure still used today – a lava rock wall • Compare modern and ancient rock wall structures • Visit a ancient Hawaiian Heiau

4. Geometry Tools Everything from a basketball to the trunks of the tallest trees has a surface area. Depending on the shape a objects surface area is easy to find. It is the total area of all faces of a figure. The formula for area is dependent on what type of shape is being measured but is best defined as length times width when dealing with a 2 dimensional square. Here are 2 examples. Sphere Surface Area= 4*pi*radius^2 The radius is 12 cm. S.A.=4*3.14*12^2 = 1808.64 cm Cylinder Surface Area=2*pi*radius* (height+radius) The radius is 24cm the height is 80cm. S.A.=2*3.14*24*104 =15674.88 cm

5. Surface Area of a Wall Now let’s find the total surface area of this wall: Length(l)=7920 feet Height(h)=7 feet Width(w)=4.5 feet h w l S.A.=2lw+2lh+2wh Answer=182223 feet Figure 1

6. Surface Area Without lwh Task 1: On your construct a diagram of a rock wall and explain how you would find the surface area without the length, width, and height dimensions. Use any shape you like for your “rocks”. WIKI Figure 2

7. Useful Terms • Similar Figures: Figures that have the same shape. They may be different sizes or angled differently. • Rotation: When a figure is turned. It’s rotation in terms of degrees is how it is measured. • Reflection: Figures that have been flipped along a line, vertical or horizontal. TASK 2: Describe on your how these terms can be useful in constructing a lava rock wall, especially in rock placement. WIKI

8. Digital Tools We will be using internet based software to consult and showcase our final presentations. Classmates can post comments and suggestions as project work progresses. There will be scheduled days for in-class project work but it is crucial to work outside of class. If you do not have access to a internet connected computer please see me. Here are some web/digital tools we will be using. You will also use a digital camera. Click on each link to use its Tutorial. WIKI FLICKR BLOGGER
