Similar Triangles Summative Project - Due Monday, November 21st

Similar Triangle Projects are due tomorrow!  Remember to include the following:

1.     Names of all group members, but you are EACH responsible for your own report.  Your   

         report should include the object’s height that was found using YOUR height. 

2.     A sketch or picture with accurately labeled data including all measurements and your  

        calculations. Be sure to use accurate measurements and do not round any values until you 

        get your final answer. 

3.     An explanation of how you found the height of your object.  Include what the object is,

        where it is located, what time you measured the shadow, and any problems you 

        encountered. 

4.     Show pride in your work with high quality drawings and written work.

Triangle Exam Tomorrow: Things to Study!

• Triangle Basics
• Finding angle measures & side lengths using equations
• Properties of altitudes (perpendicular lines, medians, and bisectors)
• Properties of isosceles triangles
• Finding length (on a graph, distance formula will be provided)
• Congruent Triangles
• Identify congruent triangles using SSS, SAS, ASA, and AAS
• Proofs (be able to fill in missing "reasons" when given "statements"
• Similar Triangles
• Know the properties of ALL similar figures (angles are congruent, sides are proportional)
• Identify similar triangles and solve for missing side lengths using proportions

Quiz Tomorrow!

There will be a short quiz tomorrow (Thursday, September 22nd) over writing equations of lines and finding midpoint and distance between two points.  Make sure you know how to:
1.  Write a line equation given 2 points
2.  Write  line equations for vertical and horizontal lines
3.  Write line equations for parallel and perpendicular lines
4.  Find the midpoint between 2 points
5.  Find the distance between 2 points

I will provide you with the formulas, you do NOT need to memorize them!
