Dividing the square with an equilateral triangle we start off with two triangles on the side and two triangles on the bottom We just have to translate the 's up to the top and we're left with 4 of the 's each having a long side length which is the same as the square side lengthThe most important rule is that this triangle has one right angle and two other angles are equal to 45 Although all right triangles have special features trigonometric functions and the Pythagorean theoremThe most frequently studied right triangles the special right triangles are the 30 60 90 Triangles followed by the 45 45 90 trianglesWhat are the angles and sides of this triangle?

15 75 90 triangle rules-R = tan 15 ∘ (This is quite easily derived from the definition of the tan function) You can also represent the ratio using radicals r = 2 − 3 ≈ If we do not want to use tan at all, then we obtain the same answer just reasoning from your picture r = 1 2 3 = 2 − 3All that remains to know the length ratios for the sides of the triangle is to determine the length of EC, its hypotenuse, via the Pythagorean Theorem

Side length rules for a triangleHowever a triangle with angles 30, 60 and 90 degrees has a property that allows you to solve your question without resorting to trigonometry The property is that the lengths of the sides of a triangle are in the ratio 12√3Although all right triangles have special features – trigonometric functions and the Pythagorean theorem The mostIf playback doesn't begin shortly, try restarting your device Videos you watch may be added to the TV's watch history and influence TV recommendations To avoid this, cancel and sign in toAn alternative (easier) method for sine and cosine of 15° and 75° is found in Ailles Rectangle (named after an Ontario high school teacher) It is easy to remember because it is two (green) 45° rightangled triangles stuck onto the sides of a (white) triangle and the rectangle completed with a (yellow) triangle on the hypotenuse of the triangle as
Rule 2 Sides of Triangle Triangle Inequality Theorem This theorem states that the sum of the lengths of any 2 sides of a triangle must be greater than the third side Rule 3 Relationship between measurement of the sides and angles in a triangle The largest interior angle and side are opposite each other By length subtraction, then, FC, the triangle's short leg, has a length of 2 – √3 A test is prudent at this point, by taking the tangent of the 15 degree angle FEC in the yellow triangle Tan (15 degrees) is equal to , which is also the decimal approximation for FC/EF, or (2 – √3)/1 All that remains to know the30 60 90 triangle sides If we know the shorter leg length a, we can find out that b = a√3 c = 2a If the longer leg length b is the one parameter given, then a = b√3/3 c = 2b√3/3 For hypotenuse c known, the legs formulas look as follows a = c/2The 45°45°90° triangle, also referred to as an isosceles right triangle, since it has two sides of equal lengths, is a right triangle in which
