Equilateral and Isosceles Triangles
This page introduces the formulas and properties of equilateral and isosceles triangles.
For equilateral triangles, the wzór na pole trójkąta równobocznego formulafortheareaofanequilateraltriangle is presented as P = a2√3 / 4, where 'a' is the side length. The wzór na wysokość trójkąta równobocznego formulafortheheightofanequilateraltriangle is given as h = a√3 / 2.
For isosceles triangles, the wzór na pole trójkąta równoramiennego formulafortheareaofanisoscelestriangle is shown as P = 1/2ah, where 'a' is the base and 'h' is the height. An alternative formula using the angle between equal sides is also provided: P = 1/2b² sin α.
Vocabulary: Equilateral triangle troˊjkątroˊwnoboczny - a triangle with all sides equal in length.
Vocabulary: Isosceles triangle troˊjkątroˊwnoramienny - a triangle with two sides of equal length.
Highlight: The relationship between the inradius r and circumradius R of an equilateral triangle is shown as R = 2r.
