What shape is a rhombus?
In plane Euclidean geometry, a rhombus (plural rhombi or rhombuses) is a quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length.
What is unique parallelogram?
In a parallelogram, opposite sides are equal, opposite angles are equal and diagonals bisect each other. A quadrilateral can be constructed uniquely if its two adjacent sides and three angles are given. • A quadrilateral can be constructed uniquely if its three sides and two included angles are given.
Can a rhombus have 4 90 angles?
No, because a rhombus does not have to have 4 right angles. A square has got 4 sides of equal length and 4 right angles (right angle = 90 degrees). A Rhombus has got 4 sides of equal length and opposite sides are parallel and angles are equal.
What polygon has four sides?
Quadrilaterals are polygons with four sides (hence the beginning “quad”, which means “four”). A polygon with non-equal sides is called irregular, so the figure that you are describing is an irregular quadrilateral. This figure has side lengths of 1, 2, 3, and 4 respectively, so it is an irregular quadrilateral.
What is a seven sided figure called?
A seven-sided shape is called a heptagon. A heptagon is one type of polygon, which can have any number of sides. A polygon is defined as a two-dimensional or plane figure that consists of line segments, which are called edges or sides. The points at which the segments meet are called vertices or corners.
What is a five sided shape called?
A five-sided shape is called a pentagon. A six-sided shape is a hexagon, a seven-sided shape a heptagon, while an octagon has eight sides…. There are names for many different types of polygons, and usually the number of sides is more important than the name of the shape.
What is the name of a seven sided shape?
shape with seven sides. In geometry, a heptagon is a seven-sided polygon or 7-gon. The heptagon is sometimes referred to as the septagon, using “sept-” (an elision of septua-, a Latin-derived numerical prefix, rather than hepta-, a Greek-derived numerical prefix; both are cognate) together with the Greek suffix “- agon ” meaning angle.
