Show values to. Additional Information The usual way of identifying a triangle is by first putting a capital letter on each vertex or corner. Like, for example, A B C. Now, a reference to A can mean either that vertex or, the size of the angle at that vertex. Here it means the size. The edges are identified by using the small version of the opposite vertex-letter. So, a is opposite A ; b is opposite B ; c is opposite C.

Please provide 3 values including at least one side to the following 6 fields, and click the "Calculate" button. A triangle is a polygon that has three vertices. A vertex is a point where two or more curves, lines, or edges meet; in the case of a triangle, the three vertices are joined by three line segments called edges. A triangle is usually referred to by its vertices. Furthermore, triangles tend to be described based on the length of their sides, as well as their internal angles. For example, a triangle in which all three sides have equal lengths is called an equilateral triangle while a triangle in which two sides have equal lengths is called isosceles. When none of the sides of a triangle have equal lengths, it is referred to as scalene, as depicted below. Tick marks on the edge of a triangle are a common notation that reflects the length of the side, where the same number of ticks means equal length. Similar notation exists for the internal angles of a triangle, denoted by differing numbers of concentric arcs located at the triangle's vertices. As can be seen from the triangles above, the length and internal angles of a triangle are directly related, so it makes sense that an equilateral triangle has three equal internal angles, and three equal length sides. Note that the triangle provided in the calculator is not shown to scale; while it looks equilateral and has angle markings that typically would be read as equal , it is not necessarily equilateral and is simply a representation of a triangle.

Thus, in this type of triangle, if the length of one side and the side's corresponding angle is known, the length of the other sides can be determined using the above triangle calculator.

Finding the missing side or angle couldn't be easier than with our great tool — right triangle side and angle calculator. Choose two given values, type them into the calculator, and the calculator will determine the remaining unknowns in a blink of an eye! If you are wondering how to find the missing side of a right triangle, keep scrolling, and you'll find the formulas behind our calculator. There are a few methods of obtaining right triangle side lengths. Depending on what is given, you can use different relationships or laws to find the missing side:.

Enter any valid input 3 side lengths, 2 sides and an angle or 2 angle and a 1 side and our calculator will do the rest. This is the acute triangle in Quadrant I, for more information on this topic, check out the law of sines ambiguous case. This is the obtuse triangle in Quadrant II, for more information on this topic, check out the law of sines ambiguous case. Status: Calculator waiting for input. The most frequent reason for this is because you are rounding the sides and angles which can, at times, lead to results that seem inaccurate. In these cases, in actuality , the calculator is really producing correct results. However, it is then rounding them for you- which leads to seemingly inaccurate results and possible error warnings. To see if that is your problem, set the rounding to maximum accuracy. Triangle App Triangle Animated Gifs. Round to.

They are similar if all their angles are the same length, or if the ratio of two of their sides is the same. Examples include: 3, 4, 5; 5, 12, 13; 8, 15, 17, etc. Are all right triangles similar? If all three sides of a right triangle have lengths that are integers, it is known as a Pythagorean triangle. The inradius is the perpendicular distance between the incenter and one of the sides of the triangle. Furthermore, triangles tend to be described based on the length of their sides, as well as their internal angles. Given the length of two sides and the angle between them, the following formula can be used to determine the area of the triangle. What's the sum of angles in a triangle? In a triangle of this type, the lengths of the three sides are collectively known as a Pythagorean triple. Please provide 3 values including at least one side to the following 6 fields, and click the "Calculate" button. Circle skirt Circle skirt calculator makes sewing circle skirts a breeze. Not all right-angled triangles are similar , although some can be. Try this helium balloons calculator! At least one dimension, of edge-length or area, has to be supplied.

The triangle length calculator tells you the length of the third side if you enter two sides and an angle. A triangle has three sides and three angles. To this end, you need to employ a sine law or the cosine law to relate them to each other.

Financial Fitness and Health Math Other. It's the third one. Data is encrypted in transit. Here it means the size. Financial Fitness and Health Math Other. Example FAQ. The perimeter is the sum of the three sides of the triangle and the area can be determined using the following equation:. Sight Words. Otherwise, the triangle will have no lines of symmetry. Likely the most commonly known equation for calculating the area of a triangle involves its base, b , and height, h.
