Another way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°. The formula gives. SSS - 3 side lengths. The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. It will even tell you if more than 1 triangle can be created. Example 1: In the simplest scenario one has measured all three sides of a triangle and then it is a matter of simple summation to find the perimeter. How do you find two sides of a triangle? The height of the triangle corresponds to its base, so whenever base length changes, height also changes.

While calculating angles and sides, be sure to carry the exact values through to the final answer. All values should be in positive values but decimals are allowed and valid. Please enter what you know about the triangle: Triangle: The calculator solves the triangle specified by three of its properties. You may adjust the accuracy of your results. Where (for brevity) it says 'edge a', 'angle B' and so on, it should, more correctly, be something like 'length of edge a' or 'edge-length' or 'size of angle B' etc. Solving Triangles given two angles and one side: If told to find the missing sides and angles of a triangle with angle A equaling 34 degrees, angle B equaling 58 degrees, and side a equaling a length of 16, you would begin solving the problem by determing with value to find first. SAS - known length of two sides and included angle. (It is the edge opposite to the right angle and is c in this case.) Any side of the triangle which is perpendicular to the height is termed as the base. Fill in 3 of the 6 fields, with at least one side, and press the 'Calculate' button. If a Data Record is currently selected in the "Data" tab, this line will list the name you gave to that data record. Also explore many more calculators covering geometry, math and other topics. The figure shows two right triangles that are each missing one side’s measure. For example, if the sides are 3 in, 4 in, and 5 in, then the perimeter is simply 3 + 4 + 5 = 12 inches in total. A = C Choose two given values, type them into the calculator and the remaining unknowns will be determined in a blink of an eye! You need only two given values in the case of: one side and one angle; two sides; area and one side; Remember that if you know two angles, it's not enough to find the sides of the triangle. This will solve for the missing length and, if you have an HTML5 compatible web browser, redraw the triangle. Solving Triangles given two angles and one side: If told to find the missing sides and angles of a triangle with angle A equaling 34 degrees, angle B equaling 58 degrees, and side a equaling a length of 16, you would begin solving the problem by determing with value to find first. It can also provide the calculation steps and how the right triangle looks. Use the law of sines to find the missing measurements of the triangles in these examples. We can find an unknown side in a right-angled triangle when we know: one length, and; one angle (apart from the right angle, that is). Fill in two (only two) values then click on Calculate. ASA - a side and 2 adjacent angles. Step-by-step explanations are provided for each calculation. We can sometimes calculate lengths we don't know yet. Fill in two (only two) values then click on Calculate. A triangle is determined by 3 of the 6 free values, with at least one side. Please input only two values and leave the values to be calculated blank. It makes the process convenient by providing results on one click. If all the inputs are angles the calculator will calculate the the proportionate length of the sides which can then be used to scale up depending on actual size requirements. A triangle is determined by 3 of the 6 free values, with at least one side. © 2006 -2021CalculatorSoup® Notice that we need to know at least one angle-opposite side pair for the Law of Sines to work. 2) Sum the squares of the 2 shortest sides.
