- Verifying a Polygon In Exercises 25-28, show that the points form the vertices of the polygon. Isosceles triangle: 1,3,3,2,2,4.arrow_forwardCentral Angle of a Tetrahedron A tetrahedron is a solid with four triangular faces, four vertices, and six edges, as shown in the figure. In a regular tetrahedron the edges are all of the same length. Consider the tetrahedron with vertices A(1,0,0), B(0,1,0), C(0,0,1), and D(1,1,1). aShow that the tetrahedron is regular. bThe center of the tetrahedron is the point E(12,12,12) the average of the vertices. Find the angle between the vectors that join the center to any two of the vertices for instance, AEB. This angle is called the central angle of tetrahedron. Note: In a molecule of methane (CH4) the four hydrogen atoms form the vertices of a regular tetrahedron with the carbon atom at the center. In this case chemists refer to the central angle as the bond angle. In the figure, the tetrahedron in the exercise is shown, with the vertices labeled H for hydrogen and the labeled C for carbon.arrow_forwardFinding the Volume of a ParallelepipedIn Exercises 69-72, find the volume Vof the parallelepiped that has u, v, and was adjacent edges using the formula V=|u(vw)|. u=2i+jv=3i2j+kw=2i3j2karrow_forward
