What shape has all equal sides?
An equilateral polygon. All regular polygons, being equilateral, will have equal sides but it is not necessary that they are regular. A rhombus, for example, is equilateral but not regular.
How many congruent faces are on a triangular prism?
The minimum numbers of congruent faces are as follows: On an equilateral triangular prism: one pair of triangles On a right equilateral triangular prism: one pair of triangles and one triplet of rectangles.
Why is an equilateral polygon not necessarily a regular polygon?
A regular polygon must be equiangular as well as equilateral. A rhombus is an example of a polygon that is equilateral but not equiangular.
How many planes of symmetry does a right prism with equilateral triangles have?
five
Why is an acute triangle not a regular polygon?
If its acute angles are different then it is not a regular polygon but if it has 3 equal acute angles of 60 degrees then it is a regular equilateral triangle
Are the two bases on a triangular prism equilateral triangles?
They can be, but they don't have to be equilateral to be a triangular prism.
How many degrees is a regular triangular prism?
If its cross-section is in the shape of an equilateral triangle then each of its 3 angles will measure 60 degrees
Can a regular polygon be equilateral?
a regular polygon is always equilateral
How do you calculate the surface area of an equalaterial trinuglar based prism?
To calculate the surface area of the equilateral triangular-based prism, you need to calculate the area of the equilateral triangle and all the other sides of the prism. The total area of all the phases will give the total surface are of an equilateral triangular based prism.
Can you construct an equilateral quadrilateral that is not regular?
No, equilateral and regular are the same thing.
A regular pentagon that is not an equilateral?
Not possible, by definition. Regular implies equilateral.
Is an equilateral pentagon regular?
No, but a regular pentagon is equilateral. Equilateral means that all sides are congruent (equal in measure); to be regular, all angles also have to be congruent.
What prism is bounded by regular polygon?
A regular prism.
What is the difference between a regular prism and an oblique prism?
an oblique prism is slanted and a regular prism is not, its right.
What shape has all equal sides?
An equilateral polygon. All regular polygons, being equilateral, will have equal sides but it is not necessary that they are regular. A rhombus, for example, is equilateral but not regular.
How many congruent faces are on a triangular prism?
The minimum numbers of congruent faces are as follows: On an equilateral triangular prism: one pair of triangles On a right equilateral triangular prism: one pair of triangles and one triplet of rectangles.
Is it true that a regular polygon is always equiangular and equilateral?
Yes, by definition. If it not equilateral AND equiangular, then it is not regular.
