Jun 5, 2023 · To calculate the isosceles triangle area, you can use many different formulas. The most popular ones are the equations: Given leg a and base b: area = (1/4) × b × √ ( 4 × a² - b² ) Given h height from apex and base b or h2 height from the other two vertices and leg a: area = 0.5 × h × b = 0.5 × h2 × a. Given any angle and leg or base. The result is not a "nice" angle like $60$ degrees or $75$ degrees, so either you give a calculator's approximation or you leave it as an expression involving $\cos^{-1}$. You could find the other two sides of the triangle using law of cosines, or you could use the Law of Sines for a spherical triangle, which is relatively easy to remember:That means that side c c c is perpendicular to the bases, and therefore equal to the height c = h c = h c = h. However, we don't know c c c, so we'll have to find it still. To do this, draw the height of our trapezoid that goes from the vertex between b b b and d d d. Together with d d d and a part of a a a, it forms a right triangle.An obtuse triangle is a triangle in which one angle is greater than 90 degrees.
