Proof that the Area of a Triangle = bh/2

Summer Math Series: Week 4 π = C/D (By observation! Since Babylonian times, where π =~ 3.125) Area of a Polygon = ½ hQ (1/2 * apothem * perimeter) Archimedes’ Proof that A = πr2. Approximate circle with inscribed (2n)-gons. Rephrasing of argument on page 93: Apolygon = ½ hQ, but: As sides ( infinity, h ( r (apothem ( radius) ................
