WebJul 28, 2024 · The sum of the angles in a triangle (on a flat plane) is 180°, and 90° + 36° + 54° = 180°. Also, cos ( θ) = sin ( 90 ° − θ), so sin 36 ° = cos 54 °; thus your findings do make sense; you simply looked at the other vertex, not the ones at the center of the circle/pentagon. WebHeron's Formula can be used to determine the area of the triangle when you know all three sides: where a, b, c are the sides and s= (1/2) (a+b+c) You could also determine the size of the central angle (C) which is also the …
