In Math, all triangles are 180°
Right angle triangle.
Acute triangle.
Equilateral triangle.
Isosceles triangle.
Obtuse triangle.
They have three sides.
They have three points.
They have three connections.
R.A.T triangles = C2 = A2 + B2
Tangent is the trigonometric function that is equal to the ratio of the sides (other than the hypotenuse) opposite and adjacent to an angle in a right-angled triangle.
Cosine is the trigonometric function that is equal to the ratio of the side adjacent to an acute angle (in a right-angled triangle) to the hypotenuse.
Since the trigonometric function is equal to the ratio of the side opposite a given angle (in a right-angled triangle) to the hypotenuse.
Pythagoras's theorem
all triangles are 180° if it is greater than 180° it wasn't a triangle.
