WebThe height of a triangle can be found through the application of trigonometry.. Knowing SAS (side-angle-side) Using the labels in the image on the right, the altitude is h = a sin .Substituting this in the formula = derived above, the area of the triangle can be expressed as: = ⁡ = ⁡ = ⁡ (where α is the interior angle at A, β is the interior angle at B, is the interior … WebYes; If two vertices (of a triangle inscribed within a circle) are opposite each other, they lie on the diameter. By the inscribed angle theorem, the angle opposite the arc determined by the diameter (whose measure is 180) has a measure of 90, making it a right triangle.
