Do the vertical cross sectional shapes of a triangular prism have all congruent triangles?
Yes the triangular cross-section area is congruent throughput the prism.
When a sphere is cut in cross section the shape formed by the cut is?
A circle.
Why was arches and triangles used in making a bridge?
Introduction of Arches reduces the bending moment at cross sections due to presence of horizontal force at the support whenever bridge is loaded and thus requirement of cross section is lesser. When triangles are easy to propagate and can have tension/compression only if used as 2-point member in bridges (forces acts only the end of any member not in between), Due to absence of bending moment it also reduces the cross-section requirement. Therefore, if we introduce arches and triangles cross section requirements of each small member get reduced.
Describe the cross-sections that are formed when a cylinder is intersected by a plane?
In Geometry, cross-section is the shape made when a solid is cut through by a plane. The cross section of a circular cylinder is a circle. * * * * * There are also cross-sections that are ellipses or rectangles.
How can you create two equilateral triangles using four matchsticks?
Cross two match sticks to bisect like X and place the other two match sticks at the base of the two equilateral triangles formed .
How many triangles does a cone have?
A cone has infinitely many triangles. Each cross-section of a cone, when cut parallel to its base, forms a triangle. As the cone tapers to a point, the triangles formed by the cross-sections become increasingly smaller and numerous. Therefore, a cone can be said to have an infinite number of triangles.
Which types of triangles can be formed by taking the cross-section of a cube?
Equilateral, Isosceles or Scalene. For the latter two they could be acute or right angled
Do the vertical cross sectional shapes of a triangular prism have all congruent triangles?
Yes the triangular cross-section area is congruent throughput the prism.
What area is formed by a plane cutting through a solid perpendicular to its axis?
A cross section is formed.
How do you work out the area of triangles?
add up the cross section and see what vthe answer is, then times it by the other part. Simple!

What is the cross section formed by a plane that contains a vertical line of symetry for a tetrahedron?
It is a triangle.

What is a cross section of a cube?
It depends on the angle of the plane of the cross section. If it is parallel to the cube's face (or equivalently, two adjacent edges) the cross section will be a square congruent to the face. If the plane is parallel to just one edge (and so angled to a face), the cross section will be a rectangle which will have a constant width. Its length will increase, remain at a maximum level and then decrease. If neither, it will be a hexagon-triangle-hexagon-triangle-hexagon (triangles when passing through a vertex).
What is a cross section of a cuboid?
A cross-section of a cuboid is the two-dimensional shape that results from cutting the cuboid with a plane. It is formed by the intersection of the plane with the three-dimensional cuboid. The cross-section of a cuboid can be a rectangle, square, or even a triangle, depending on how the cuboid is cut. The shape and size of the cross-section will vary based on the orientation and angle of the cutting plane relative to the cuboid.
