## Pythagorean theorem powerpointPresentation Transcript

• Created By: Kenshae Clair Ill By: Kenshae Clair Pythagoren Theorem and Distance Formula
• Pythagorean Theorem is related to the three sides of a right triangle. It states that c 2 = a 2 + b 2 , C is opposite the right angle which is referred to as the hypotenuse.
• 2. If the height of a triangle is five inches less than the length of its base, and if the area of the triangle is 52 squared inches, find the base and the height.
• 3. The Pythagorean Theorem only works on right triangles, but it will work on any right triangles.
What is Pythagorean Theorem? What do the variable Stands for? What type of triangle do we use the theorem for?
• Draw a Right Triangle with two labeled sides with numbers.
• C 2 = a 2 + b 2
• x 2 = 6 2 + 8 2
• X 2 = 36 + 64
• X 2 = 100
• X 2 = 10
• Given two points (X1 , Y1) and ( X2, Y2), the distance between these points is given by the formula: square root of x2 –x1 squared + y2 – y1 squared.
• The distance 'd' between the points A = (x1, y1) and B = (x2, y2) is given by the formula: This formula is an application of Pythagoras' theorem for right triangles:
What is the Distance Formula? What steps do you follow to use the distance formula?
• (4, -3) 2 + ( 7, 2) 2
• 7- 4 2 + 2- (-3)
• 3 2 + 5 2
• + 25 = 34
• 5.83
List two points Use the distance formula to find the distance between the two points
