1.5 Using Formulas in Geometry
Perimeter: Sum of the side lengths of a figure
Area: Number of non-overlapping square units of a given size that exactly cover a figure
Diameter: Segment that passes through the center of the circle, and whose endpoints are on the circle
Radius: Segment whose endpoints are the center of the circle and a point on the circle
Circumfrance: Distance around the circle
Pi: The Ratio of a circle’s circumfrance to its diameter, it is rational and can be approximated as 3.14 or 22/7
Rectangle Equations
P= 2(Length)+2(Width)
A= L*W
Square Equations
P= 4s (4* sides)
A= s^2 (Sides squared)
Triangle Equations
P=a+b+c (sides a, b, and c)
A= ½bh (base*height)
