WebSince obtuse vertex angle EAB = 108 and two equal base angles have sum = 180 – 108 = 72, acute base angles such as CAB = 36 degrees. Also, angle CAD = angle EAB - 2*36 = 36 degrees, so the 2 diagonals from a vertex such as A trisect the vertex angle; that is, they divide the vertex angle into 3 equal 36-degree angles. WebMar 28, 2024 · Substituting h into the first area formula, we obtain the equation for the equilateral triangle area: area = a² × √3 / 4. 2. Using trigonometry. Let's start with the trigonometric triangle area formula: area = (1/2) × a × b × sin (γ), where γ is the angle between the sides. We remember that all sides and all angles are equal in the ...
WebFeb 2, 2024 · An exterior angle of a triangle is equal to the sum of the opposite interior angles. Every triangle has six exterior angles (two at each vertex are equal in measure).
