Enter the length of any side to calculate the length of the other two sides in addition to the perimeter and the area

A 30-60-90 triangle is a type of right triangle that is widely used in mathematics and geometry. This triangle has three angles, measuring 30 degrees, 60 degrees, and 90 degrees, and its sides are in a specific ratio. The most notable property of the 30-60-90 triangle is its ratio of sides. The triangle is constructed with a shorter leg, a longer leg, and a hypotenuse. The length of the shorter leg is half the length of the hypotenuse, while the longer leg is equal to the shorter leg multiplied by the square root of three.

Another property of the 30-60-90 triangle is its angles. The triangle has one angle measuring 90 degrees, which makes it a right triangle. The other two angles measure 30 degrees and 60 degrees, respectively. These angles are important in trigonometry, which calculates the values of sine, cosine, and tangent functions.

We have the following observations about the side length ratio of the triangle:

➢ The side opposite the 30° angle: = x

➢ The side opposite the 60° angle: = x√3

➢ The side opposite the 90° angle: = 2x

The sides of a 30-60-90 triangle are always in the ratio of 1 : √3 : 2.

Applications of the 30-60-90 Triangle: The 30-60-90 triangle has various applications in different fields of study. The 30-60-90 triangle is commonly used in a variety of applications, including architecture, engineering, and physics. One of its most important applications is in trigonometry, where it is used to solve for the lengths of sides in certain trigonometric functions. For example, the sine, cosine, and tangent functions can be used to find the length of the sides of a 30-60-90 triangle. The sine of the 30-degree angle is equal to the length of the side opposite the 30-degree angle divided by the length of the hypotenuse. The cosine of the 30- degree angle is equal to the length of the side adjacent to the 30-degree angle divided by the length of the hypotenuse. And the tangent of the 30-degree angle is equal to the length of the side opposite the 30-degree angle divided by the length of the side adjacent to the 30-degree angle. The 30-60-90 triangle is also important in engineering and architecture, where it is used to design and build structures with angled supports, such as roofs and bridges. In these applications, the 30-60-90 triangle is used to calculate the angles and lengths of the supports needed to ensure the stability and safety of the structure. Calculating the Sides of a 30-60-90 Triangle To calculate the sides of a 30-60-90 triangle, you need to know the length of one of the sides. Let's call the length of the side opposite the 30-degree angle "𝑥".Then, according to the ratios we mentioned earlier, the length of the side opposite the 60-degree angle is √3 times the length of the side opposite the 30-degree angle, or √3𝑥. And the length of the hypotenuse is twice the length of the side opposite the 30-degree angle, or 2𝑥.

The 30 60 90 triangle calculator is an online tool that can be used to solve for various properties of a 30-60-90 triangle. Here are some key points about how it works:

The calculator uses formulas based on the ratios of the sides in a 30-60-90 triangle to solve for the unknown values. For example, if you know the length of the shorter leg (𝑎), the calculator can use the formula 𝑏 = 𝑎√3 and 𝑐 = 2𝑎 to find the lengths of the other sides.

The calculator can also be used to find the area and perimeter of the triangle. The formula for the area is 𝐴 = 1/2 × 𝑏 × ℎ, where 𝑏 is the base of the triangle and h is the height. The perimeter is simply the sum of the lengths of the three sides.

If you are dealing with a triangle that is not a 30-60-90 triangle, the calculator may not be able to solve for all the properties. However, there are other online tools available for solving other types of triangles. let's say we are given a 30-60-90 triangle with a hypotenuse of length 10 cm. We can use the ratios we mentioned earlier to find the lengths of the other two sides. According to the ratios, the side opposite the 30-degree angle is half the length of the hypotenuse. So: Length of side opposite 30-degree angle = (1/2) × 10 𝑐𝑚 = 5 𝑐𝑚 The side opposite the 60-degree angle is √3 times the length of the side opposite the 30-degree angle. So: Length of side opposite 60-degree 𝑎𝑛𝑔𝑙𝑒 = √3 × 5 𝑐𝑚 = 5√3 𝑐𝑚 And the hypotenuse is twice the length of the side opposite the 30-degree angle. So: Length of hypotenuse = 2 ×5 𝑐𝑚 = 10 𝑐𝑚 Therefore, the sides of the 30-60-90 triangle with a hypotenuse of length 10 cm are:

➢ Side opposite the 30-degree angle = 5 𝑐𝑚

➢ Side opposite the 60-degree angle = 5√3 𝑐𝑚

➢ Hypotenuse = 10 𝑐𝑚

We can also check our answer using the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. In this case: (5 𝑐𝑚)2+ 𝑥(5√3𝑐𝑚)2 = (25 𝑐𝑚)2 + (75 𝑐𝑚)2 =100𝑐𝑚2 𝐴𝑛𝑑: (10 𝑐𝑚)2= 100𝑐𝑚2 So, our answer checks out
