MATH Q3 TERMS

• The Distance Formula If A (x1 and y1) and B (x2 and y2) are any two points on the coordinate plane then ....
• Midpoint Formula If A(x1,y1) and B(x2,y2) are any two points on the coordinate plane then the midpoint of AB has the coordinates
• Center Radius form or standard form is (x-h)2 + (y-k)2=r2
• The equation of a circle centered at the origin x2+y2=r2
• The General form of equation of a circle is x2+y2+dx+ey+F=0
• Guidelines for Placing Figures on a Coordinate Plane 1. Use the origin as the vertex or center. 2. Place at least one side of a polygon on an axis. 3. Keep the figure within the first quadrant, if possible. 4. Use coordinates that will make computations as easy as possible.
• Coordinates in proof uses formulas to prove statements are true or not true.
