What is Circumference?C=πr C=πd Length= cm, m, in, ft, units
Area of a squareA=S squared =LxW =BxH =units squared, cm squared, in squared,m squared, ft squared
Area of a RectangleA=LxW =BxH units sq, cm sq, in sq, ft sq, m sq
Area of a TriangleA=1/2 BH (base + height have to meet @ 90*
Area of a ParallelogramA=BxH (base + height have to meet @ 90* units sq, cm sq, in sq, ft sq, m sq
Area of a TrapezoidA=1/2 H (B1+B2) B1+B2 have to be parallel (B+H have to meet @ 90*)
Area of a circleA=π r2 units2, cm2,m2,in2, ft2
RadiusLine segment from the edge of the circle to the center of the circle r=1/2d
DiameterLine segment from edge to edge through the center of the circle d=2r
Complementary2 angles that when added equal 90* (sum) angle ABC + angle CBD=90*
Supplementary Angles2 angles that when added equal 180* angle a + angle b=180*
Adjacent angles2 angles that are next to each other thatshare a vertex angle x + angle z =180*
Vertical angles2 angles that are oppisite share the same mearusement angle x= angle y
Volume of a Cubevol=LxWxH =5 triple units 3, cm 3, ft 3, cubic units
