Eureka Math Grade 7 Module 6 Lesson 16 Example Answer Key<\/h3>\n

Example 1.
\nConsider a ball B. Figure 3 shows one possible slice of B.
\na. What figure does the slicing plane form? Students may choose their method of representation of the slice (e.g., drawing a 2D sketch, a 3D sketch, or describing the slice in words).
\n\"Engage
\nb. Will all slices that pass through B be the same size? Explain your reasoning.
\nc. How will the plane have to meet the ball so that the plane section consists of just one point?
\nAnswer:
\na. A circle (or disc)
\nb. No, different slices can result in circles of different sizes; it will depend on where the slicing plane meets the ball.
\nc. If you picture the ball and the plane as distinct but being brought toward each other, the plane section of just one point occurs when the plane just makes contact with the ball.<\/p>\n

Example 2.
\nThe right rectangular prism in Figure 4 has been sliced with a plane parallel to face ABCD. The resulting slice is a rectangular region that is identical to the parallel face.
\n\"Engage
\na. Label the vertices of the rectangular region defined by the slice as WXYZ.
\nb. To which other face is the slice parallel and identical?
\nc. Based on what you know about right rectangular prisms, which faces must the slice be perpendicular to?
\nAnswer:
\na. \"Engage
\nb. The slice is parallel and identical to the face EFGH.
\nc. Since the slice is parallel to two faces, it will be perpendicular to whichever sides those faces are perpendicular to. Therefore, the slice is perpendicular to faces ABHG, CDFE, BCEH, and ADFG.<\/p>\n

Example 3.
\nThe right rectangular prism in Figure 6 has been sliced with a plane perpendicular to BCEH. The resulting slice is a rectangular region with a height equal to the height of the prism.
\n\"Engage
\na. Label the vertices of the rectangle defined by the slice as WXYZ.
\nb. To which other face is the slice perpendicular?
\nc. What is the height of rectangle WXYZ?
\nd. Joey looks at WXYZ and thinks that the slice may be a parallelogram that is not a rectangle. Based on what is known about how the slice is made, can he be right? Justify your reasoning.
\nAnswer:
\na. \"Engage
\nb. The slice is perpendicular to the face ADFG.
\nc. 6 in.
\nd. The slice was made perpendicular to face BCEH. Then we know that the angles in the slice, \u2220X and \u2220Y, formed by the slicing plane and face BCEH, are right angles. If we focus on \u2220X of the slice, since it is a right angle, we know that \\(\\overline{W X}\\) must be perpendicular to face BCEH. \\(\\overline{W X}\\) lies in face ABCD, which is perpendicular to both BCEH and to ADFG, so \\(\\overline{W X}\\)is perpendicular to ABCD. This means that \\(\\overline{W X}\\) must also be perpendicular to \\(\\overline{W Z}\\). A similar argument can be made for \u2220Y of the slice, making all four angles of WXYZ right angles and making WXYZ a rectangle.<\/p>\n

Eureka Math Grade 7 Module 6 Lesson 16 Exercise Answer Key<\/h3>\n

Exercise 1.
\nDiscuss the following questions with your group.
\nThe right rectangular prism in Figure 5 has been sliced with a plane parallel to face LMON.
\n\"Engage
\na. Label the vertices of the rectangle defined by the slice as RSTU.
\nb. What are the dimensions of the slice?
\nc. Based on what you know about right rectangular prisms, which faces must the slice be perpendicular to?
\nAnswer:
\na. \"Engage
\nb. 10 cm \u00d7 11 cm
\nc. Since the slice is parallel to two faces, it will be perpendicular to whichever sides those faces are perpendicular to. Therefore, the slice is perpendicular to faces JKLM, JMOP, NOPQ, and KLNQ.<\/p>\n

In the following exercises, the points at which a slicing plane meets the edges of the right rectangular prism have been marked. Each slice is either parallel or perpendicular to a face of the prism. Use a straightedge to join the points to outline the rectangular region defined by the slice, and shade in the rectangular slice.
