WebSine, Cosine and Tangent. Sine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle:. For a given angle θ each ratio stays the same no matter how big or small the triangle is. To calculate them: Divide the length of one side by another side WebThese two triangles are congruent. Step-by-step guide: Congruent shapes. Congruent triangles; Congruent triangles also have special conditions of congruence. These involve looking at their sides and angles. The four conditions are known by abbreviations: SSS (three sides the same), RHS (right-angled triangle, hypotenuse and a side the same),
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 … WebPearson qualifications Edexcel, BTEC, LCCI and EDI Pearson ...
