Fórmulas Triángulo rectángulo

$$2p = i + c_{1} + c_{2}$$

Perímetro

$$A = \frac{c_{1} \times c_{2}}{2}$$

Área

$$c_{1} = \frac{A \times 2}{c_{2}}$$

$$c_{2} = \frac{A \times 2}{c_{1}}$$

$$A = \frac{i \times h}{2}$$

Área

$$i = \frac{A \times 2}{h}$$

$$h = \frac{A \times 2}{i}$$

$$i = \sqrt{ {c_{1}}^2 + {c_{2}}^2 }$$

Teorema de Pitágoras

$$c_{1} = \sqrt{ {i}^2 - {c_{2}}^2 }$$

$$c_{2} = \sqrt{ {i}^2 - {c_{1}}^2 }$$

$$i : c_{1} = c_{1} : p_{1}$$

Primer Teorema de Euclides

$$i : c_{2} = c_{2} : p_{2}$$

Primer Teorema de Euclides

$$p_{1} : h = h : p_{2}$$

Segundo Teorema de Euclides

$$i = c \sqrt{2}$$

$$c = \frac{i}{\sqrt{2}}$$

$$A = \frac{{c}^2}{2}$$

$$A = \frac{{i}^2}{4}$$

$$c = \sqrt{2A}$$

$$i = c_{1} \times 2$$

Hipotenusa

$$c_{1} = \frac{i}{2}$$

Cateto menor

$$c_{2} = c_{1} \sqrt{3}$$

Cateto mayor

$$c_{1} = \frac{c_{2}}{\sqrt{3}}$$

Cateto menor

$$c_{2} = i \frac{\sqrt{3}}{2}$$

Cateto mayor

$$i = c_{2} \frac{2}{\sqrt{3}}$$

Hipotenusa
