Do these three points make a right triangle?
A = ( 2 , -1) , B= ( -2 , -3) , C= ( -4 , 2)
Type your answers as a simplified radical.
What is the distance between point A,( 2 , -1) and point B ( -2 , -3)?
What is the distance between point A,( 2 , -1) and point C ( -4 , 2)?
What is the distance between point C,( -4 , 2) and point B ( -2 , -3)?
Now use the Pythagorean Theorem. Do the squares of the the two short sides add to the square of the longer side?
Distance from A to B squared is
Distance from A to C squared is
Distance from C to B squared is
Do the three points form a right triangle?
