How do you know if a triangle is right angled
WebJan 31, 2024 · To calculate the area of an equilateral triangle, you only need to know the side: area = a² × √3 / 4. Since √3 / 4 is approximately 0.433, we can formulate a quick recipe: to approximate the area of an equilateral triangle, square the side's length and then multiply by 0.433. Although we didn't make a separate calculator for the ...
