Triangles A triangle is a special right triangle defined by its angles It is a right triangle due to its 90° angle, and the other two angles must be 30° and 60° 345, and Right Triangles 345 and triangles are special right triangles defined by their side lengthsA triangle is a right triangle with angle measures of 30º, 60º, and 90º (the right angle) Because the angles are always in that ratio, the sides areThanks to all of you who support me on Patreon You da real mvps!

The other one is the 45 45 90 triangle These triangles are special triangles because the ratio of their sides are known to us so we can make use of this information to help us in right triangle trigonometry problems In the case of the triangle, their side's ratios are 1The reason these triangles are considered special is because of the ratios of their sides they are always the same!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 triangles
Right triangle calculator, 30 60 90 formula, 45 triangle, special area, unit circle calculator 45 45 90 triangle calculator is a dedicated tool to solve this special right triangle Find out what are the sides, hypotenuse, area and perimeter of your shape and learn about 45 45 90 triangle formula, ratio and rules If you want to know more about another popular right triangles, check out this 30 60 90 triangle tool and the calculator forMultiply this answer by the square root of 3 to find the long leg Type 3 You know the long leg (the side across from the 60degree angle) Divide this side by the square root of 3 to find the short side Double that figure to find the hypotenuse Finding the other sides of a triangle when you know the hypotenuse
The property is that the lengths of the sides of a triangle are in the ratio 12√3 Thus if you know that the side opposite the 60 degree angle measures 5 inches then then this is √3 times as long as the side opposite the 30 degree so the side opposite the 30 degree angle is 5 Triangle Practice Name_____ ID 1 Date_____ Period____ ©v j2o0c1x5w UKVuVt_at iSGoMfttwPaHrGex rLpLeCkQ l ^AullN Zr\iSgqhotksV vrOeXsWesrWvKe`d\1Find the missing side lengths Leave your answers as radicals in simplest form 1) 12 m n 30° 2) 72 ba 30° 3) x y 5 60° 4) x 133y 60° 5) 23 u v 60° 6) m n63The ratio of the sides follow the triangle ratio 1 2 √3 1 2 3 Short side (opposite the 30 30 degree angle) = x x Hypotenuse (opposite the 90 90 degree angle) = 2x 2 x Long side (opposite the 60 60 degree angle) = x√3 x 3

Another rule is that the two sides of the triangle or legs of the triangle that form the right angle are congruent in length Knowing these basic rules makes it easy to construct a triangle Constructing a Triangle The easiest way to construct a triangle is as follows Construct a square four equal sides to the Special right triangle 30 60 90 with hypothenuse measuring 8 cm The ratio for this special right triangle is {eq}1 \sqrt {3} 2 {/eq} We Because it is a special triangle, it also has side length values which are always in a consistent relationship with one another The basic triangle ratio is Side opposite the 30° angle x Side opposite the 60° angle x * √ 3 Side opposite the 90° angle 2 x

For any problem involving a 30°60°90° triangle, the student should not use a table The student should sketch the triangle and place the ratio numbers Since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½ Example 2 Evaluate sin 30° Answer sin 30° = ½ You can see that directly in the figure above The triangle is a special right triangle, and knowing it can save you a lot of time on standardized tests like the SAT and ACT Because its angles and side ratios are consistent, test makers love to incorporate this triangle into problems, especially on the nocalculator portion of the SATPlan Use the properties of a 30°60°90° Right Triangle to find the legs Add the sides to get perimeter Shorter Leg (SL) opposite the 30° angle = 1/2 Hypothenuse = 1/2 (8 cm) = 4 cm Longer Leg (LG) = √3 x shorter = 4√3 cm Perimeter (P) = Hypothenuse SL LG = 8 4 4√3 = 12 4√3 cm or P ≈ 13 cm
