The Triangle
In geometry, a triangle is a three-sided polygon.
Four common classifications of triangles are equilateral, (three equal sides and three equal interior angles), isometric,(two equal sides and two equal interior angles), right angle, (one of the interior angles must equal 90°, and scalene triangle, (three unequal sides).
If you add all the interior angles of a triangle they must equal 180°.
