The national flag of Timor-Leste (bandeira nacional de Timor-Leste; bandeira nasionál) consists of a red field with the black isosceles triangle based on the hoist-side bearing a white five-pointed star in the center superimposed on the larger yellow triangle, also based on the hoist-side, that extends to the center of the flag.

"The national flag is rectangular and is formed by two isosceles triangles, the bases of which are overlapping. One triangle is black and its height is equal to two-third of the length overlapped to the yellow triangle, whose height is equal to half the length of the Flag. In the centre of the black triangle there is a white star of five ends, meaning the light that guides. The white star has one of its ends turned towards the left side end of the flag. The remaining part of the flag is red.” Wikipedia
