The document discusses the Pythagorean theorem and distance formula. The Pythagorean theorem is used to find the length of the hypotenuse of a right triangle given the lengths of the two legs. The distance formula is used to calculate the distance between two points and involves subtracting the x-coordinates and y-coordinates of the points and squaring and summing the results. An example of each formula is provided and worked through step-by-step.

Pythagreon theorem and distance formula power point
- 1. By: Lawrence McDonald Pythagorean Theorem and Distance Formula
- 2. What is the Pythagorean Theorem? Pythagorean Theorem is a formula used to find the size of a triangle. What do the variables stand for ? A and B is the legs of the triangle and Hypotenuse What type of triangle do we use the theorem for ? Right Triangle
- 3. Pythagorean Theorem Ex: 6 3 X 3 2 +6 2 =X 2 9+36=45 45=X 2 X = 6.7
- 4. What is Distance Formula ? A Formula to find the distance between two points Steps to solving a distance formula problem : 1. Label the points Ex; x1,y1_x2,y2 2. Put them in the distance formula Ex: (x2 – x1) 2 + (y2 – y1) 2 3. Do the math
- 5. Distance Formula Ex: (10,16) (1,4) (10-1) 2 +(4-16) 2 (9) 2 +(12) 2 81+144 225 ( Square Root It ) 15
