Scribe Post, Andrew Braden, Ch.4 and 5 Polygons

Today we went over Altitude, Classifications of triangles, and Isosceles triangles.  We went over how to find the altitude of the different triangles.  Where the altitudes would/could be measured on the triangles.

 

Altitude- is a perpendicular segment that joins a vertex of a triangle to the opposite side.


Right Triangle- a right triangle is a triangle where one of its interior angles is a right angle.


Obtuse Triangle- An obtuse triangle is a triangle in which one of the angles is an obtuse angle.


Acute Triangle- An acute triangle is a triangle in which all three angles are acute angles.

 

Isosceles Triangle- An isosceles triangle is a triangle with two equal sides.


IF you are given one angle in an isosceles triangle you can find three possibilities for the other two angles using big parts equals small parts.  You also know that two angles must always be the same.

If you are given


Then your possibilities are

 







 

 

 I am going to choose Charles for tommorrows scribe.

  1. Nice post, Andrew, you might wanna take off that last name though.

    Also I have a question for anyone who wants to answer me, is the altitutude one perpendecular segment that joins a vertext of a triangle to the oppose side? Because if so isn't thre three different altitudes as there are three of these segments? Or is the altitude tghe sum of the leinghts of theses segments? I think that it is the former but I am not sure so if someone could just comment back and let me know that would be great.
    Nice post Andrew.

  2. The altitude is a vertex of a triangle that can be joined to the opposite side by a line. Sorry that was a little late but i hope it helps.
