This free triangle calculator computes the edges, angles, area, height, perimeter, median, as well as other values and a diagram of the resulting triangle.

A triangle has three sides and three angles. The three angles always add to 180°. There are three special names given to triangles that tell how...

A triangle has three internal angles, each one bounded by a pair of adjacent edges; the sum of angles of a triangle always equals a straight angle (180 degrees or π radians). The triangle is …

A triangle is a closed, two-dimensional shape that has 3 sides, 3 angles, and 3 vertices. It is the polygon with the fewest sides. Since it is the simplest form of a polygon, any polygon can be …

Triangle Calculator (This free online tool lets calculates all sides and angle measurements based on your input and draws a free downloadable image of your triangle!)

It is usual to name each vertex of a triangle with a single capital (upper-case) letter. The sides can be named with a single small (lower case) letter, and named after the opposite angle.

Test your understanding of Triangles with these 10 questions. You probably like triangles. You think they are useful. They show up a lot. What you'll see in this topic is that they are far more …

Triangles are polygons (shapes) with three sides and three angles, which can be formed by connecting any three points in a plane. They are one of the first shapes studied in geometry.
