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!!

Chantelle Bsaid...Don't think that way. Draw it out and it will come to you!! I wouldn't have put this on if I did not think you could do it!

Mr. Hsaid...Great Problem. Will get the kids to do it tomorrow in class. If you add a picture they would understand it more. Great Idea.

Mr. Hsaid...To insert a picture make sure it is a .png or jpg. If you made one in paint you need to save as .jpg. Then upload to blogger using the image button on your toolbar.
