You can use the Pythagorean theorem and height of the right triangles within the equilateral to determine the missing side lengths of an equilateral triangle. Substituting h into the first area formula, we obtain the equation for the equilateral triangle area: area = a * 3 / 4. Make sure that you have plenty of room to draw all three sides! So for example, if you have an equilateral triangle where each of the sides was 1, then its area would be square root of 3 over 4. The equilateral triangle is the simplest regular polygon. The area of the equilateral triangle is given, hence: 100 = a23 4. It is known that the area of a triangle is given as 1/2 Base Height. To calculate the area of the triangle, multiply the base (one side of the equilateral triangle) and the height (the perpendicular bisector) and divide by two. Draw a 30-60-90 triangle and its reflection about the leg opposite the 60 angle. Therefore, we have proved the formula for the height of an equilateral triangle. Using trigonometry. Equilateral triangles have three lines of reflective symmetry, the lines joining each vertex to the midpoint of the opposite side. a = c2 - b2 b = c2 - a2 The law of cosines is a generalization of the Pythagorean theorem that can be used to determine the length of any side of a triangle if the lengths and angles of the . Then, you can use the formula A = 3/4 (a) to determine the area of an equilateral triangle.
