如何计算Rhombus
learn.whatIsHeading
Calculates rhombus area, perimeter, and diagonal lengths. Specializes parallelogram with equal sides.
公式
Area = (d₁ × d₂) / 2 where d₁, d₂ = diagonals
分步指南
- 1Area = (d₁ × d₂) / 2 where d₁, d₂ = diagonals
- 2Perimeter = 4 × side
- 3Diagonals bisect at 90° and each other
- 4Side = √((d₁/2)² + (d₂/2)²)
例题解析
输入
d1=8, d2=6
结果
Area 24
常见错误注意事项
- ✕Using side length for area (wrong formula)
- ✕Confusing diagonal with side in calculations
常见问题
What's the difference between rhombus and square?
Rhombus: equal sides, no angle requirement; square: equal sides AND all angles 90°.
Why is diagonal formula d₁ × d₂ / 2?
Diagonals divide rhombus into 4 right triangles; area = sum of triangles.
