and

C G

make in the regular heptagon

A B C D E F G

. (See the picture.)

180^{\circ} - (\frac{360^{\circ}}{14} + 3 \cdot \frac{360^{\circ}}{14})

180^{\circ} - (\frac{360^{\circ}}{7} + 3 \cdot \frac{360^{\circ}}{7})

180^{\circ} - \frac{360^{\circ}}{14} + 3 \cdot \frac{360^{\circ}}{14}

180^{\circ} - (\frac{360^{\circ}}{14} + 4 \cdot \frac{360^{\circ}}{14})
