Exercise 4.3 Find the Angles

For this exercise, you will be searching and identifying angles in an image. You will be working on the image below of the NASA building and adding lines.

Materials needed:

Depending on if you have a printer or not, there are two different options available.

Option #1 – Preferred

• 4B pencil, Sharpie, or ball point pen – any type of pen that will show up on printer paper.
• A 8.5X11 inch print of the below NASA image (in color or black and white) – The print should be as big as possible on the paper with minimum margins. For the exercise, you will add the necessary angles to the printed image and take a photo of it. Make sure all added angles show up on the image after you take a photo of it.

Option #2 This may work if you do not have a printer, however, it may be less precise and hard to fit everything. Keep it neat.

• Viewfinder and erasable marker
• Have the NASA image pulled up on a computer monitor. Line up and place the viewfinder over the image on the monitor. Make sure the image is as large as possible in the viewfinder window. Draw the needed information on the viewfinder with your wet or dry marker.  Take a photo of your monitor with the viewfinder aligned and attached with the finished work on it.

Time to complete: 20 minutes. Use the full 20 minutes to work on this exercise.

Instructions:

Find at least 8 individual features that have notable angles in the image below. Draw a distinct line along the angled feature on the image. Next, turn the line into an arrow and note along the line what time the angle is pointing to. Note, an angled line without a pointer can actually give two times. For instance a perfectly horizontal line will give a time of 3:00 or 9:00 and a vertical line a time of 12:00 or 6:00. Try to spread out the arrows and keep the area neat and easy to understand.

Group the photo of your finished image with exercises 4.2-4.5 in one file when submitting your work. Do not submit exercises 4.2, 4.3, 4.4, and 4.5 as individual files. If using a viewfinder, take individual images of each exercise and combine them into one file.

Note: In the image below there is an arrow on the ground in the parking lot. This is a really short arrow and a little difficult to tell the angle, however, it is close to the 1:30 mark, since it looks to be half way between 12:00 and 3:00. This angle could be marked 1:30, but don’t use this one, find your own angles. Remember, if you are drawing this image, you can check that same arrow on your drawing and it will give the same time, if drawn correctly.
