Today we learned how to find the orthocenter of a triangle. The orthocenter is the point of concurrency of altitudes of a triangle.
This weekend's homework is P. 323 #17-22, and 29-31. Also, we will have a quiz on 5.1-5.4 on Monday. Please review the Study Project terms through "orthocenter" and be sure you know the properties of segments in a triangle. If you were absent today, please email me for the list of terms you are responsible for knowing by Monday.
Please the following animation to help you understand orthocenters: http://www.classzone.com/cz/books/geometry_2007_na/resources/applications/animations/geom07_ch05_pg321.html
i wasnt at school on friday, and i dont know what an altitude of a triangle is. i looked in the text book but im still confused. anything i should know that would help me? thanks

did you check out the animation i posted on this post? the altitude of a triangle is just the height of a triangle (a perpendicular segment from a vertex to its opposite side- not necessarily a bisector). you need to know where the three altitudes of a triangle meet (the orthocenter) for acute, right, and obtuse triangles. that's all. if you are still haven't trouble. come see me at lunch tomorrow in the library.
