1. The most precise name for a space figure with four lateral faces that are triangles is a tetrahedron.
2. The most precise name for a space figure with three lateral faces that are rectangles is a rectangular prism.
3. The most precise name for a space figure with a lateral surface and one circular base is a cylinder.
To find the most precise name for each space figure with the given properties, we need to understand the characteristics of different three-dimensional shapes.
1. A space figure with four lateral faces that are triangles is called a triangular pyramid. To determine this, we can recall that a pyramid is a polyhedron with one base (which can be any polygon) and triangular faces connecting the base to a single vertex.
2. A space figure with three lateral faces that are rectangles is called a rectangular prism. By definition, a prism is a polyhedron with two parallel and congruent bases connected by flat faces (known as lateral faces). In this case, since the lateral faces are rectangles, we specifically refer to it as a rectangular prism.
3. A space figure with a lateral surface (side) and one circular base is called a cone. We can recognize this by knowing that a cone has a single circular base and a curved surface (lateral surface) that tapers to a point called the apex or vertex.
In general, understanding the properties and characteristics of different shapes helps us to determine their precise names.
