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 are equivalent to each other in Plane Geometry.

The Alternate Interior Theorem states that if two lines cut by a transversal line have a pair of congruent alternate interior angles, then they must be parallel. Prove this theorem in Neutral Geometry (first 4 axioms) in two ways 1) using the exterior angle theorem 2) then without. Hint: use proof by contradiction for both solutions.

Consider a rectangular coordinate system in the plane, in the usual sense of analytic geometry. Every point has a pair of coordinates (x,y). For the purposes of this question, let us regard points as indistinguishable from the ordered pairs (x, y) that describe them. Thus every figure, that is, every set of points, becomes a collec- tion of ordered pairs of real numbers. Under what conditions, if any, do the following figures represent functions? (a) a triangle, (b) a single...

Please show and answer all the parts of this question. Suppose that in manufacturing a very sensitive electronic component, a company and its customers have tolerated a 2% defective rate. Recently, however, several customers have been complaining that there seem to be more defectives than in the past. Given that the company has made recent modifications to its manufacturing process, it is wondering if in fact the defective rate has increased from 2%. For quality assurance purposes, you decide to...

a. What is the value of neutron flux considering Source-free, Non-multiplying Systems with Plane Geometry, if Φ (x) = 3.3 X 1013 x2 and Diffusion Length, L = 2.85 cm. If you get negative value, consider the absolute term for neglecting the negative sign. [15] b. What is the value of neutron current density? Assume Φ (x) = 3.3 X 1013 x and Diffusion Length, L = 2.85 cm and ∑a = 2.1 X 104 cm-1? [15]
