Hey Everyone! I'm not sure if Mr. H want's me to write here, {please let me know if this is bad haha} but my name is Chantelle and I am going to the U of Regina and have been invited to your Blog!!!

I came across a question in one of my math classes that I feel will be right up your alley with Pythagorean Theorem! So here is a little challenge for you!

The question is: The perimeter of an isosceles triangle {2 sides are equal and the two angles at the base are equal} ABC with AB=BC is 128 inches. The altitude {height of the triangle which is perpendicular (90 degree angle) to the base ( and in the case of an isosceles triangle, hits at the midpoint of the base)} BD is 48 inches. What is the area of the triangle??

So, you will need a couple formulas other than just pythagorus. However, I think you can do it!
This is from my Math 308 class, which is a 4th year math class!!!

Good Luck!!

Scibe for Tuesday March 10th By Kim Ramirez 8-17

Today in class Mr. Harbeck talked with us about perfect squares. He showed us how to take two or more perfect squares and turn it into one perfect square. Some homework was assigned to us and the homework is we have to make perfect squares rangeing from squares numbering from 1-16. Here is something that will help

Today in class we work on squares. And we copied down a times table that was 12x12.It looked something like this.















For homework we had to high light or colour the equal squares.But once we finished that it looked like this.













Also in class we had to answer the following:
1x1=1 16x16=
2x2=4 17x17=
3x3=9 18x18=
4x4=16 19x19=
5x5=25 20x20=
6x6=36 21x21=
7x7= 22x22=
8x8= 23x23=
8x9= 24x24=
10x10= 25x25=
11x11= 26x26=
12x12=144 27x27
13x13= 28x28
14x14= 29x29
15x15= 30x30=
Sorry it wasnt finished =(

Today was our video project day, we were supposed to prove the Pythagoras theorem. The 6 and 8 are the legs and the hypotenuse is 10 of the whole right angle triangle,below is a video of the proof.






The video below you is how to do the equation and how it works.

This video is the proof of the equation and how it all works together.
