What does the white triangle on the Philippine flag mean?

Answer 1

The white triangle stands for equality and fraternity; the blue field for peace, truth and justice; and the red field for patriotism and valor. The eight primary rays of the sun represent the first eight provinces (Batangas, Bulacan, Cavite, Laguna, Manila, Nueva Ecija, Pampanga, and Tarlac) that sought independence from Spain and were placed under martial law by the Spaniards at the start of the Philippine Revolution in 1896.[5] The three stars represent the three major geographical divisions of the country: Luzon, the Visayas, and Mindanao.
