Example # 05: Predict a triangle along with its terms with the following given information: $$ a = 2 $$ $$ mA = 60^\text{o} $$ $$ mB = 20^\text{o} $$ Solution: As we are given two angles and one side . Hanna Pamua, PhD candidate b c deg Check out 18 similar triangle calculators Like the 30-60-90 triangle, knowing one side length allows you to determine the lengths of the other sides . The factors are the lengths of the sides and one of the two angles, other than the right angle. There are also special cases of right triangles, such as the 30 60 90, 45 45 90, and 3 4 5 right triangles that facilitate calculations. You can use any of the formulas below to calculate the angles, sides, area, or perimeter of the right triangle. To enter a value, click inside one of the text boxes. For right triangles only, enter any two values to find the third. : Then using the known ratios of the sides of this special type of triangle: As can be seen from the above, knowing just one side of a 30-60-90 triangle enables you to determine the length of any of the other sides relatively easily. They are similar if all their angles are the same length, or if the ratio of 2 of their sides is the same. Right triangle calculator exemplifies this truth by taking in two values (one side and any other value) and returning all missing values in exact value and decimal form while displaying the formulas and calculation process for each of the missing values. example 3: Find the hypotenuse if and leg . These sides of the triangle are straight line segments such that two sides meet at each vertex of the triangle to form a three-sided closed figure. Find the missing leg using trigonometric functions: As we remember from basic triangle area formula, we can calculate the area by multiplying triangle height and base and dividing the result by two. This formula is known as the Pythagorean Theorem. There are a few methods of obtaining right triangle side lengths. In this case the SAS rule applies and the area can be calculated by solving (b x c x sin) / 2 = (10 x 14 x sin (45)) / 2 = (140 x 0.707107) / 2 = 99 / 2 = 49.5 cm 2. Right Triangle.
