This week we will be discussing the Pythagorean Theorem, which is an idea that came from the ancient Greeks about the right triangle.
The basic principle behind this idea is that if a triangle has a right angle and you made a square on each of the three sides, then the biggest square has the exact same area as the other two squares put together.
Here’s a right triangle. The hypotenuse is the longest side of the triangle.
This week, please take the time to watch the following videos to assist you with your learning of Pythagorean Theorem. This concept builds upon the Square Roots that we learned today and will be something that you will truly love to work out because they are so easy!
Also, any commenting on these 4 videos will be for extra credit. Remember to use the 3-2-1 Response method and number the things so I can easily read them.
Pythagorean Theorem Practice is due on Friday. I will also be taking a grade on your class notebook on Friday. You will need to have the following 5 things for a 100...

Introduction to Pythagorean Theorem
ReplyDelete3 things I learned
1. The box lets you know that the triangle is 90 degrees
2. If you know 2 sides you can always figure out the 3rd one
3. The longest side is called the hypotenuse
2 things that stuck
1. Once you identify the hypotenuse you label the sides c,a or b
2. A hypotenuse is opposite of the 90 degree angle
1 thing I have a ? about
1. Are the two sides equal ?
Pythagorean Theorem 1
ReplyDelete3 things I know
1.You need to draw out the picture to make it easier.
2.as you read the question make sure too draw it out
3.You use the same formula once you draw it out.
2 things i have questions about
1.What if the shape isn't a triangle.
2. Does the same formula apply.
1 thing that stuck
1. Draw and label.
Pythagorean Theorem 2
ReplyDelete3 things that I learned
1.The usually tell you the length of two sides and you find the 3rd side.
2.Some of the squares of the shorter side might be equal to the one on the longest side.
3.The longest one is opposite to the 90 degree angle.
2 things I have a ? about
1. Why are some of the squares the same?
2. Why do you have to find the perfect square for c ?
1 thing that stuck
1. The hypotenuse is the longest side.
Pythagorean Theorem 3
ReplyDelete3 things that stuck
1.The diagonal of the carpet is the square root.
2.Most problems need you to find the width.
3.A triangle has a 90 degree for you to find it out with a Pythagorean theorem.
2 things I have a ? about
1.Why do we use squared as a or b ?
2. How do you find out the number when it has no perfect square.
1 thing that stuck
You can regroup and borrow if you don't have enough numbers
Introduction to Pythagorean Theorem
ReplyDelete3 things i learned-
-I learned how to use the Pythagorean Theorem.
-I learned how to find the hypotenuse.
-I learned how to identify a right triangle.
2 things i still have questions about-
-Why does he do the subtracting part different?
-Do we have to do the subtracting part the same way he does?
1 thing that stuck-
-a2+b2=c2
Pythagorean theorem 1
ReplyDelete3 things i learned-
-We use the Pythagorean theorem in every day life, well if you sail.(:
-Figuring out the hypotenuse isn't hard at all.
-i can figure out the hypotenuse if i have the other 2 sides.
2 things i still have questions about-
-Why would you need to figure out the length of the rope?
-What happens if your only know one side?
1 thing that stuck-
-You can figure it out if you have at least to sides.
Pythagorean theorem 2
ReplyDelete3 things i learned-
-I learned how to find the side of a right triangle.
-I learned that this guy does it differently then we were taught.
-I learned that this is easier than i thought it was.
2 things i still have questions about-
-Why do we have to have exponents in the equation?
-Who came up with the Pythagorean theorem?
1 thing that stuck-
-If you have the hypotenuse and one side, you can figure out the other side.
pythagorean theorem 3
ReplyDelete3 things i learned-
-Most problems you have to figure out one side.
-A right triangle has a 90 degree angle in it.
-I learned that a square cut in half is a right triangle.
2 things i still have questions about-
-How do you find on of the sides when it isn't a right triangle?
-how do you find the area of that triangle?
1 thing that stuck-
-If you cant solve the problem out in your head do it on paper.
Nice, I'm only in fifth grade and i have trouble doing my math journal. Please help me!
