Web• Two tangents on a circle that meet at a point outside the circle are equal in length. So AC = BC. • The angle in a semicircle is a right angle. So angle ABC = 90°. • When two angles are subtended by the same arc, the angle at the centre of a circle is twice the angle at the circumference. So angle AOB = 2 × angle ACB. Weblaw of tangents : a law in plane trigonometry: in any plane triangle the tangent of one half the difference of any two angles is to the tangent of one half their sum as the difference of the sides opposite the respective angles is to the sum of those sides Love words?

The law of tangents can be used to compute the missing side and angles of a triangle in which two sides a and b and the enclosed angle γ are given. From one can compute α − β; together with α + β = 180° − γ this yields α and β; the remaining side c can then be computed using the law of sines.
