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.
When actual values are entered, the calculator output will reflect what the shape of the input triangle should look like. Triangles classified based on their internal angles fall into two categories: right or oblique. The longest edge of a right triangle, which is the edge opposite the right angle, is called the hypotenuse.
Any triangle that is not a right triangle is classified as an oblique triangle and can either be obtuse or acute. There are multiple different equations for calculating the area of a triangle, dependent on what information is known.
Likely the most commonly known equation for calculating the area of a triangle involves its base, b , and height, h. The "base" refers to any side of the triangle where the height is represented by the length of the line segment drawn from the vertex opposite the base, to a point on the base that forms a perpendicular.
Given the length of two sides and the angle between them, the following formula can be used to determine the area of the triangle. Note that the variables used are in reference to the triangle shown in the calculator above. Another method for calculating the area of a triangle uses Heron's formula. Unlike the previous equations, Heron's formula does not require an arbitrary choice of a side as a base, or a vertex as an origin.
However, it does require that the lengths of the three sides are known. The median of a triangle is defined as the length of a line segment that extends from a vertex of the triangle to the midpoint of the opposing side.
A triangle can have three medians, all of which will intersect at the centroid the arithmetic mean position of all the points in the triangle of the triangle. Refer to the figure provided below for clarification. The medians of the triangle are represented by the line segments m a , m b , and m c. If the longitude is given in W as west, the number should be preceded by a minus sign.
Decimal degree WGS Since this converter calculates with negative north values instead of positive south values, you have to put a - in front of your value, if it contains the specification S. So from Since this converter calculates with negative east values instead of positive west values, you have to put a - in front of your value, if it contains the specification W.
The input for the longitude must be between and and must be integer. The input of minutes for latitude and longitude is an optional decimal number, but if it is made it must be between 0 and If these limits are not met, the frame will turn red or the fields will remain empty.
Degrees Minutes WGS Since this converter calculates with negative north values instead of positive south values, you have to add a - in front of your degree value, if it contains the specification S. Since this converter calculates with negative east values instead of positive west values, you have to put a - in front of your degree value, if it contains the specification W.
The input of minutes for latitude and longitude must be between 0 and 59 and must be integer. The input of the seconds for latitude and longitude is optional, but if it is done it must be between 0 and If these limits are not met during input, the frame will turn red or the fields will remain empty. Since this converter calculates with negative north values instead of positive south values, you have to add a - to your degree value, if it contains the specification S.
The northernmost point is about The southernmost point is about The easternmost point is about The westernmost point is about 5.
If these limits are not met, the frame turns red or the fields remain empty. Example: Zone 32U East value North value The zone determines the rough position of the point and should prevent mix-ups. Valid zone values are from 01AX, but without O and I. Eastern values must be between North values must be between 1 and 9,, If these limit values are not adhered to during input, the frame turns red or the fields remain empty.
The letter of the zone is corrected automatically with wrong input. Z: E: N:. East values must be between 1 and 99, Missing digits are filled in at the back. North values must be between 1 and 99, Missing digits are padded at the back.
Values below 10, must be filled with zeros at the front so that the two numbers are 5 digits long each. The letter of the zone is automatically corrected if the input is incorrect.
The northernmost point is about 56 degrees and therefore the maximum value for H is The southernmost point is about 46 degrees and therefore the minimum value for H is The most westerly point is about 5 degrees and therefore the maximum value for R is The easternmost point is about 16 degrees and therefore the minimum value for R is Gauss Kruger Bessel, Potsdam.
Zone: R: E H: N. The length can be between 1 and 6 characters. Example: sifts.
