App description

Parallelogram calculation formula:

1. Parallelogram area \(S = bh = absinθ\)

2. Parallelogram perimeter \(C = 2a + 2b\)

3. \(short diagonal = √(a^2 + b^2 - 2abcos(θ))\)

4. \(long diagonal = √(a^2 + b^2 - 2abcos(π - θ))\) <!-- <img src="http://www.yunsuan.org/static/upload/07/0792c012-0b03-11e8-ac99-00163e053731_m.jpg" /> -->
