- Now we can find the angle at the top point of the star by adding the two equal base angles and subtracting from 180°. 72° + 72° = 144° 180° - 144° = 36° So each point of the star is 36°. You wanted the sum of the points interior angles of the points. There are 5 of them, so 5 times 36° is 180°. Edwin
