Finding length the hypotenuse Now let’sthe apply the of Pythagorean is easy ifto you

Finding length the hypotenuse Now let’sthe apply the of Pythagorean is easy ifto you knowdistance the perfect Theorem finding between squares to 400 two points C 2 = a 2 + b 2 C 2 = 52 + 122 C 2 = 25 + 144 C 2 = 169 5 BUT WHAT DOES C equal? 12 C = 13 169

How could you use the Pythagorean Theorem to find the length of segment AB.

How could you use the Pythagorean Theorem to find the length of segment AB. Y What is the RISE from A to B? C 6 B What is the RUN from A to B? 9 C-2 3==a 62 + b 2 13 What kind of triangle do we have? 2 = 62 + 132 C C= 205 C 2 = 36 + 169 . (3, 5) What is the length of segment AB A What is the approximate length of C= 205 . (9, 18) What is the length of segment AB? A C 2 = 205 BUT WHAT DOES C equal? 18 – 5 = 13 X

Now let’s see if you can find the length of a line segment on

Now let’s see if you can find the length of a line segment on a coordinate plane 1. Take a sheet of graph paper one team of 4 students. 2. Set up the x and y axis where the origin is on the center of the graph paper. 3. Plot the point A(1, 4) and point B(6, 9) 4. Now what is the length of segment AB

Work in a group of 4 • One team member will set up the

Work in a group of 4 • One team member will set up the x and y axis and plot Point A(1, 4) and Point B(6, 9) • The 2 nd team member will determine the RISE • The 3 rd team member will determine the RUN. • The 4 th team member will determine the length of line segment AB.

Now Change your Jobs 1. Plot the points 2. Determine the length of the

Now Change your Jobs 1. Plot the points 2. Determine the length of the RISE 3. Determine the length of the RUN. 4. Determine the length of the SEGMENT What is the length. CD C(3, 8) D(5, 10) EF E(0, 7) F(4, 11) GH G(5, 9) H(9, 6)
