Document Summary
Identify each of the following as true or false. Two lines can separate a plane into 3 disjoint regions. ____ c. two spheres can intersect in a line. ____ d. a pentagonal-based prism has 7 faces. _____ f. every convex polyhedron is a platonic solid. _____ g. the sum of the exterior angles of a regular pentagon is 360 degrees. Use the given angle information to determine the measures of the angles indicated with letters. 84 e a = c = d = e = f = Suppose that a ray of light hits the curved reflective surface shown below at some point p, at an angle of. 25 degrees to the normal to the surface at point p. (note that the normal is given in the diagram. ) Sketch the ray of light and label all relevant measurements. Then draw the trajectory of the reflected light, being sure to label exactly how the light is reflected on your diagram.
