What is lateral edge?
What is lateral edge?
A lateral edge is the intersection of two lateral faces. Sometimes, the lateral edge of a prism and the altitude are the same. That’s called a right prism because the lateral edge makes a right angle with the base.
What is a lateral face on a polyhedron?
A prism is a polyhedron whose faces consist of two congruent polygons lying in parallel planes and a number of parallelograms. The parallelograms are called the lateral faces of the prism. The segments that join the bases and form the sides of the lateral faces are called the lateral edges of the prism.
What is the edge of a polyhedron?
A line segment where two faces of a polyhedron meet, also called a side.
How many edges does a polyhedron have?
Every polyhedron has three parts: Face: the flat surfaces that make up a polyhedron are called its faces. These faces are regular polygons. Edge: the regions where the two flat surfaces meet to form a line segment are known as the edges….Comprehensive Curriculum.
|Name||No. of faces|
|Decahedron||A polyhedron with 10 faces|
Are the lateral edges of a prism congruent?
The lateral edges are parallel and congruent. All cross sections of a prism parallel to the bases will be congruent to the bases. Prisms are named for the shape of the bases. (as shown in both the left and right diagrams).
Can a polyhedron have 10 faces 20 edges and 15 vertices?
Q8. Can a polyhedron have 10 faces, 20 edges and 15 vertices? Euler;s formula can’t be proved. Hence,a polyhedron can not have 10 faces,20 edges and 15 vertices.
Can a polyhedron have 8 faces 14 edges and 6 vertices?
No, a polyhedron cannot have 8 faces, 26 edges and 16 vertices.
Is an edge the same as a side?
In a polygon, an edge is a line segment on the boundary, and is often called a side.
Can a polyhedron have 13 faces 20 edges and 15 vertices?
Answer Expert Verified No.It can’t have 10 faces , 20 edges, and 15 vertices as The formula i.e. Euler’s formula isn’t being satisfied.
Can a polyhedron have 10 faces 20 edges and 15 vertical?
Are lateral area and volume the same?
Surface area and volume are different attributes of three-dimensional figures. Surface area is a two-dimensional measure, while volume is a three-dimensional measure. Two figures can have the same volume but different surface areas.
What are the edges of a polyhedron called?
The line segments created by two intersecting faces are called edges. The vertices are points where three or more edges meet. The hexagonal prism above is a polyhedron that has 6 lateral faces that are parallelograms, and 2 faces on the top and bottom, called bases, that are hexagons.
What are the lateral edges of a pyramid?
A pyramid is a solid with one base and lateral faces that meet at a common vertex. The edges between the lateral faces are lateral edges and the edges between the base and the lateral faces are base edges. A cube is made of six identical faces.
How to calculate the lateral edge of a tetrahedron?
In other words, a tetrahedron is a solid bounded by four triangular faces. Formula: a = 3h/ √area Example: Calculate the lateral edge of the Tetrahedron in which its height and area measurements be 60 cm and 45 cm respectively. a = (3 x 60)/ √45 Lateral Edge of the Tetrahedron = 26.832815732 cm
Which is the lateral edge of a cube?
The edges between the lateral faces are lateral edges and the edges between the base and the lateral faces are base edges. A cube is made of six identical faces. The lateral surface of a cube is the face on its sides, side of faces ‘a’ or edges is know as lateral edges. A pyramid on a triangular base is called a tetrahedron.
