Pythagorean Theorem and Distance formula

ByLadasha Johnson

Pythagorean Theorem Explanation Slide• Pythagorean Theorem is a2 +

b2= c2. The variables a and b stands for the legs of the triangle, and c stands for the hypotenuse. We always use a right triangle for the theorem.

Pythagorean Theorem Example Slide• My right triangle.

8

6

x

A2+ b2= c2

82+ 62= c2

64 + 36= 100 square root= 10

Distance Formula

• Distance formula is ( x1- x2) ( y1- y2).

• The steps that you follow to use the distance formula is label the points, (x1- y1) (x2- y2), and after that you do the math.

Distance Formula Example Slide• (4,9) (16,3) 4= x 9= y 16=x 3=y• 4-16= -122 9-5= 42

• -122= 144 42= 16• 144+16= 160 • Square root 160=12.94
