Prove the following problems using the complex plane model of Euclidean geometry, in the spirit of Erlangen Program: 1. Prove that the diagonals of a parallelogram bisect each other. 2. Prove that the sum of the squares of the diagonals of a parallelogram is equal to the sum of the squares of all the sides of the parallelogram. 3. Prove the Cosine Law for triangles: In a triangle with the sides a, b, and c, the square of the side opposite C = is expressed as c2 = a2 + b2 - 2 b a cos . 4. Prove the theorem: The bisector of an angle of a triangle divides the opposite side into two segments which are proportional to the sides that include the angle.

Prove the following for Euclidean Geometry. Provide general dynamic illustrations in GeoGebra. You will have to break down your illustrations and your proofs into 3 cases. Case 1: Both sides of the angle are tangent to the circle. Case 2: Exactly one side of the angle is tangent to the circle. Case 3: Neither side of the angle is tangent to the circle. Proposition 129. If an angle intercepts two arcs of a circle, then the measure of the angle...

Answer the following parts in Plane Geometry: (a) Show that the converse to the alternate interior angles theorem postulate implies the angle sum postulate in Plane Geometry. (Hint: Check out Euclid Book 1 Prop 32 for the idea, but make sure you write an axiomatic Plane Geometry argument.) (b) Show that the angle sum postulate implies the converse to the alternate interior angles theorem. (Hint: Draw a perpendicular.) (c) Explain why that means you can conclude that the two statements...
