Questions tagged [triangle]

Triangles are simple, yet fundamental building blocks of many different mathematical fields including trigonometry and geometry.

There are 6 types of triangles including:

  • Equilateral

    All edges are the same length.

    enter image description here

  • Isosceles

    Two edges are the same length.

    enter image description here

  • Scalene

    All edges are different lengths.

    enter image description here

  • Right
