Spectrum Math Grade 2 Chapter 7 Lesson 7.4 Drawing Solid Shapes Answers Key
Answer the questions.
What two plane shapes make up a square pyramid?
Answer:
A square pyramid consists of a square base and four triangles connected to a vertex. Its base is a square and the side faces are triangles with a common vertex. A square pyramid has three components. A three-dimensional geometric shape having a square base and four triangular faces/sides that meet at a single point (called a vertex) is called a square pyramid. It is called a pentahedron, due to its five faces. A square pyramid has:
– An apex: top vertex or point of the pyramid
– A Base in a square shape
– Four triangular faces
What plane shape is used to make a cube?
Answer:
The plane shape is used to make a cube a square.
– It has all its faces in a square shape.
– All the faces or sides have equal dimensions.
– The plane angles of the cube are the right angle.
– Each of the faces meets the other four faces.
– Each of the vertices meets the three faces and three edges.
What two plane shapes can be part of a rectangular solid?
Answer:
The two plane shapes are rectangle and square.
– A rectangular prism has 6 faces, 12 edges and 8 vertices
– The top and base of the rectangular prism are always a rectangle
– Like a cuboid, it also has three dimensions, i.e., length width and height
– Pairs of opposite faces are identical or congruent.
What plane shape is most like a sphere?
Answer:
The plane shape is a circle.
The shape of a sphere is round and it does not have any faces. The sphere is a geometrical three-dimensional solid having a curved surface. Like other solids, such as cubes, cuboids, cones and cylinders, a sphere does not have any flat surface or a vertex or an edge. The real-life examples of the sphere are:
– Basketballs, World Globe, Marbles, Planets, Moon.
Look at the shape.
rectangular solid
Draw your own shape. Color it.
Answer:
– A rectangular prism has 6 faces, 12 edges and 8 vertices
– The top and base of the rectangular prism are always a rectangle
– Like a cuboid, it also has three dimensions, i.e., length width and height
– Pairs of opposite faces are identical or congruent.
cube
Draw your own shape. Colour it.
Answer:
A cube is a 3-D solid shape, which has 6 faces. A cube is one of the simplest shapes in three-dimensional space. All six faces of a cube are squares, a two-dimensional shape.
sphere
Draw your own shape. Colour it.
Answer:
the sphere is a geometrical figure that is round in shape. The sphere is defined as a three-dimensional space. The sphere is three dimensional solid, that has surface area and volume. Just like a circle, each point of the sphere is at an equal distance from the centre.
square pyramid
Draw your own shape. Colour it.
Answer:
A square pyramid is a three-dimensional geometric shape that has a square base and four triangular sides that are joined at a vertex. It is a polyhedron (pentahedron) with five faces. A square pyramid consists of a square base and four triangles connected to a vertex. Its base is a square and the side faces are triangles with a common vertex.
A square pyramid has three components.
– The top point of the pyramid is called the apex.
– The bottom square is called the base.
– The triangular sides are called faces.
