直角三角形(勾股定理)计算器
勾股定理 | c2 = a2 + b2 |
面积 | a × b / 2 |
c边的高 (h) | a × b / c |
a边角平分线 | 2 × b × c × Cos(A/2) / (b + c) |
b边角平分线 | 2 × a × c × Cos(B/2) / (a + c) |
c边角平分线 (tc) | tc2 = 2 × a2 × b2 / (a + b)2 |
a边中位线 ( ma ) | ma2 = b2 + 0.25 × a2 |
b边中位线 ( mb ) | mb2 = a2 + 0.25 × b2 |
c 边中位线( mc ) | mc = c / 2 |
内切圆半径 | a × b / ( a + b + c ) |
外接圆半径 | c / 2 |
