distance formula video

distance formula

1) distance formula for the points (-4,3) and (6,-2)  .

2) substitute the points into the formula .

if any numbers are negative remember to keep up with signs .

3) add or subtract the numbers .

4) square the numbers , this will always be a positive number . 

5)  add your squares .

6) approximate using calculator .

7) simplify to 5 on the square root 5 .

math

ABC and DFE are complementary angles and angle DEF is supplementary

math

ADC is equal to 90 degrees

acute / obtuse

angle CBD is acute while angle ABC is obtuse

8/27/10 misc. angle info

ABD= right angle ( 90 degrees )
angle CBD and angle ABC are both supplementary angles . angle ABD is a complementary angle it is also perpendicular .
