1 Make sense of problems and persevere in
solving them.
You identified parallel planes and intersecting
planes in three dimensional figures.
•  Draw isometric views of three-dimensional
figures.
•  Investigate cross sections of threedimensional figures.
•  isometric view
•  cross section
Use Dimensions of a Solid to Sketch a Solid
Use isometric dot paper to sketch a triangular
prism 6 units high, with bases that are right
triangles with legs 6 units and 4 units long.
Which diagram shows a rectangular prism 2 units
high, 5 units long, and 2 units wide?
Use an Orthographic Drawing to Sketch a Solid
Use isometric dot paper and the orthographic
drawing to sketch a solid.
Which diagram is the correct
corner view of the figure given
the orthographic drawing?

Identify Cross Sections of Solids
BAKERY A customer ordered a two-layer sheet
cake. Determine the shape of each cross section
of the cake below.
A solid cone is going to be sliced so that the
resulting flat portion can be dipped in paint and used
to make prints of different shapes. How should the
cone be sliced to make prints in the shape of a
triangle?
