WebOA = OX since both of these are equal to the radius of the circle. The triangle AOX is therefore isosceles and so ∠OXA = a. Similarly, ∠OXB = b. Since the angles in a triangle add up to 180, we know that ∠XOA = 180 - … WebLearn Geometry skills for free!

WebIn trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles. According to the law, where a, b, and c are the lengths of the sides of a triangle, and α, β, and γ are the opposite angles (see figure 2), while R is the radius of the triangle ... WebScalene Triangle. No equal sides. No equal angles. How to remember? Alphabetically they go 3, 2, none: Equilateral: "equal" -lateral (lateral means side) so they have all equal sides. Isosceles: means "equal legs", and we have two legs, right? Also i SOS celes has two equal "S ides" joined by an " O dd" side. WebClear. Use the calculator above to calculate the area of a triangle. Enter any two values and the other will be calculated. For example: enter the base and altitude and press 'Calculate'. The area will be calculated. Similarly, if you enter the area and base, the altitude needed to get that area will be calculated. charlbury farm riding school
