3. Prove the side-side-side congruence test following the steps below. Assume that A, B, C, resp. D, E, F are three non-collinear points and the corresponding segments are congruent, that is, AB 본 DE, BC EF and CA FD. (Your ultimate goal will be to show that AABCADEF, that is, the angles corresponding to each other are also congruent; for example, CAB4FDE, and so on.) (a) Prove that there exists a point C such that line AB separates C and...

Let A, B, C, and D be four distinct points in the plane. Suppose that no three of them lie on a line and A, C are on opposite sides of the line BD. The lengths of the line segments AB, BC, CD and DA are 1, 2, 3 and 4 respectively. (a) What is the range of possible values for the length x of the line segment BD? You should justify your answer carefully! [5 marks] (b) Now suppose...

Let A-B-C denote B is between A and C. For this problem, use the following three axioms: A1: Each pair of points is assigned a number, called the distance between A and B. it is denoted by AB. A2: Given any points A and B, then AB 20. Equality holds precisely when A=B. A3: For all points A and B, ABEBA Suppose A, B, C, and D are collinear. Assume that A-B-C means: A, B, and C are distinct, collinear...
