153 Lesson MA 16 Outline Answering of homework questions over lesson 15. Lesson 16 Section 3.1 Rectangular Coordinate System y Q II QI x Q IV Q III Example: Plot the point ( 2, 4 ) on the above axes Distance Formula If A ( x1 , y1 ) and B ( x2 , y2 ) , then the distance between A and B is given by d ( A, B ) = ( x2 x1 ) + ( y2 y1 ) 2 2 Example: Find the distance between A ( 5, 3) and B ( 2, 3) y x Midpoint Formula If A ( x1 , y1 ) and B ( x2 , y2 ) , the midpoint is: x1 + y1 x2 + y2 , 2 2 Example: Find the midpoint of A ( 5, 3) and B ( 2, 3) Example: Given A ( 2, 5) , find B ( x, y ) so M ( 3, 1) is the midpoint of AB . Perpendicular Bisector C B If C is on the perpendicular bisector of AB , then M A d ( A, C ) = d ( B, C ) Example: Find the coordinates of point C so that C is on the perpendicular bisector of AB where A ( 4, 3) and B ( 6,1) . Given is C ( x,11) Example: Find the area of the triangle ABC given: A ( 8, 5 ) C ( 3, 2 ) B (1, 2 )
