Measuring interior angles of triangles
WebAn equilateral triangle is a triangle in which all sides are equal and all interior angles are congruent. Each angle of an equilateral triangle measures $60^\circ$. Alt tag: An equilateral triangle ABC. In the equilateral triangle ABC shown below, the area of the triangle is the green shaded region. Alt tag: Area of an equilateral triangle WebSimilarly, 8 triangles can also be drawn in a concave decagon. Since the sum of the angles of a triangle is 180°, the sum of the interior angles of a dodecagon is 8 × 180° = 1440°. A regular decagon has equal interior …
