# Bangun datar bahasa inggris

Bangun datar adalah salah satu konsep dasar dalam matematika yang memegang peranan penting dalam pembelajaran geometri. Dalam bahasa Inggris, istilah-istilah ini digunakan untuk menggambarkan berbagai bentuk geometri yang kita temui sehari-hari. Mari kita bahas beberapa nama-nama bangun datar dalam bahasa Inggris beserta deskripsi singkatnya.

Square (Persegi)

A square is a four-sided polygon with all sides of equal length and all angles of 90 degrees. It is a regular quadrilateral.

Rectangle (Persegi Panjang)

A rectangle is a four-sided polygon with opposite sides of equal length and all angles of 90 degrees. Unlike a square, it does not have all sides of equal length.

Triangle (Segitiga)

A triangle is a three-sided polygon. There are different types of triangles, including equilateral triangles (with all sides and angles equal), isosceles triangles (with two sides and two angles equal), and scalene triangles (with no equal sides or angles).

Circle (Lingkaran)

A circle is a two-dimensional shape with all points equidistant from its center. It is defined by its radius or diameter.

Pentagon (Lima Sisi)

A pentagon is a five-sided polygon. It can have equal sides (regular pentagon) or sides of different lengths.

Hexagon (Enam Sisi)

A hexagon is a six-sided polygon. It can be regular (with equal sides and angles) or irregular (with sides and angles of different measures).

Octagon (Delapan Sisi)

An octagon is an eight-sided polygon. Like other shapes, it can be regular or irregular.

Rhombus (Belah Ketupat)

A rhombus is a four-sided figure with all sides of equal length but with opposite angles not necessarily equal.

Trapezoid (Trapesium)

A trapezoid is a four-sided figure with one pair of parallel sides. The other two sides are not parallel.

Parallelogram (Persegi Panjang)

A parallelogram is a four-sided figure with opposite sides that are parallel. The opposite angles are also equal.

Ellipse (Elips)

An ellipse is a curved, closed shape that resembles a circle but is stretched or compressed along one axis.

Quadrilateral (Bujur Sangkar)

A quadrilateral is a four-sided polygon. It's a general term that encompasses various shapes, including squares, rectangles, parallelograms, and trapezoids.

Kite (Layang-Layang)

A kite is a four-sided shape with two pairs of adjacent sides that are equal in length. The angles between these sides can vary.

Regular Polygon (Poligon Beraturan)

A regular polygon is a shape with all sides and angles of equal measure. Regular polygons can have different numbers of sides, such as triangles, squares, and hexagons.

Irregular Polygon (Poligon Tidak Beraturan)

An irregular polygon is a shape with sides and angles of different lengths and measures. It does not fit the definition of a regular polygon.

Sector (Sektor)

A sector is a portion of a circle enclosed by two radii and the arc between them. It is measured in degrees.

Crescent (Bulan Sabit)

A crescent is a two-dimensional shape with two circular arcs on opposite sides, forming a shape similar to the moon in its crescent phase.

Star (Bintang)

A star is a two-dimensional shape with various points radiating from a central point. The number of points can vary, creating different types of stars.

Oval (Oval)

An oval is a two-dimensional shape that is similar to an ellipse but with more symmetry.

Heart (Hati)

A heart is a two-dimensional shape with two lobes at the top and a pointed bottom, representing the symbol of love.

Diamond (Permata)

A diamond is a four-sided figure with equal-length diagonals that intersect at right angles. It resembles a rhombus.

Cylinder (Silinder)

A cylinder is a three-dimensional shape with two circular bases and a curved surface connecting them.

Cube (Kubus)

A cube is a three-dimensional shape with six equal square faces and 12 equal edges.

Cone (Kerucut)

A cone is a three-dimensional shape with a circular base and a curved surface that tapers to a point called the apex.

Sphere (Bola)

A sphere is a three-dimensional shape with all points on its surface equidistant from its center.

Pyramid (Piramida)

A pyramid is a three-dimensional shape with a polygonal base and triangular faces that converge to a single point called the apex.

Rectangular Prism (Prisma Segiempat)

A rectangular prism is a three-dimensional shape with rectangular faces. It has 12 edges and eight vertices.

Triangular Prism (Prisma Segitiga)

A triangular prism is a three-dimensional shape with triangular bases and rectangular sides.

Torus (Torus)

A torus is a three-dimensional shape that resembles a doughnut or inner tube, with a circular cross-section.

Polyhedron (Polihedron)

A polyhedron is a three-dimensional solid with flat faces. It can have various shapes and numbers of faces, edges, and vertices.
