Theorem 3-8 Converse of the Same-Side Exterior ...SAS Postulate (Side-Angle-Side) If two sides and the included angle of one triangle are congruent to the corresponding. parts of another triangle, then the triangles are congruent. A key component of this postulate (that is easy to get mistaken) is that the angle. must be formed by the two pairs of congruent, corresponding sides of the triangles.Notice the distinction between the above examples. Example 1.1 is an unknown angle problem because its answer is a number: d = 102 is the number of degrees for the unknown angle. We call Example 1.2 an unknown angle proof because the conclusion d = 180 − b is a relationship between angles whose size is not specified. EXAMPLE 1.3.semicircle is 90˚, angle XWZ is not 90˚ so XZ cannot be a diameter. c) Work out the size of angle a 62.5˚ Give a reason for your answer The angle between the tangent and the side of a circumscribed triangle is equal to the opposite internal angle of the triangle, so angle XWZ = angle between XZ and the tangent = 2a = 125˚, so a = 62.5˚ a a ...
