 **Tutorial #60: Comparing Similar and Congruent Figures

media type="file" key="Comparing Similar to Congruent Figures.mp3"

This picture was taken from []** =Congruent- Two pairs of figures whose relative sides are of equal length. Another word for equal is congruent. The relative angles of two congruent figures must have equal measures.=

This picture was taken from **[]** =Similar- Similar figures are the same shape but not the same size. The relative sides of two similar figures are not congruent but the sides of one figure to another have the same relation. For example, a side of triangle ABC has a length of two. The side in relation to that on triangle DEF has a length of four. The relation of triangle ABC to triangle DEF would be 2:4 or 1:2. The relative angles of two similar figures are congruent. To find the perimeter of a figure, you add all of its side lengths. To find the relation of the perimeter of one figure to another, you add up all of the sides of each figure and divide it by the other. To find the relation of the area of one figure to the other, you square, or multiply the figure's perimeter by itself, and then divide by the second figure. For example 4x4:8x8=16:64=1:4. To find the relation of the volume of one figure to another, you cube, or multiply the figure's perimeter by itself, twice, and then divide by the second figure. For example, 4x4x4:8x8x8=64:512=1:8.=

Reflection

1. On my original geometry podcast, Mrs. Jennings gave me a 60/75, while the college students gave me a 10.4/25. At first, I felt the scores were a little unfair because I worked very hard on my tutorial. But after I read the comments I started to understand and agree more with my not-so-great grade. I think the scores are accurate because I didn't make my tutorial for someone who was not a geometry student. The terminology I used was for someone who understood angles and geometry. Also I agree with my grade because it was confusing how I had my podcast on one page and my visual component on another. I should have put them on the same page. Also my links did not work. People had to cut and paste them into a search engine. The comments were helpful because they made me realize what I needed to fix in my tutorial. If I did not get the comments, I would have never realized what I was doing wrong.

2. I changed the visual component of my tutorial by editing some of the terminology and making it more basic. This made the visual component easier for someone who has not taken geometry to understand. Another change I made to my tutorial was putting the podcast and the visual component on one page. This made it easier to navigate and follow along the tutorial. One more change I made to my tutorial was putting my links on the webpage instead of a pdf. This made my links work without having to cut and paste them into a search engine.

3. What I would tell next year's geometry students is to make sure they put themselves in the perspective of someone who would be viewing the tutorial. I didn't understand how confusing my tutorial was until I read the comments and saw that it didn't make complete sense. I would also tell next year's geometry students to double-check their links and make sure that everything is working. To help manage their time, they should get all of their research done and gather all of their pictures at least 3 days before the due date. They should have everything ready to be put on the wiki. Once everything is ready, they should upload it onto their wiki. I recommend having everything ready before they upload anything on their wiki so they make sure they will have no problems finding information at the last minute.

4. I learned many things about technology when making my tutorial. I learned what a podcast was, and how to make one. Podcasts can apply to education because you can use them to spread knowledge through audio. I also learned how to make a page and upload it to a wiki. This can be applied to education because you can spread knowledge through websites and the internet.
