Sector. Definition: The part of a circle enclosed by two radii of a circle and their intercepted arc. As you can see from the figure above, a sector is a pie-shaped part of a circle. It has two straight sides (the two radius lines), the curved edge defined by the arc, and touches the center of the circle.

Besides, what do you call the shape of a pizza slice?
Sectors are shaped like a slice of pizza, with a curved edge and each straight side the same length as the radius of the circle, or pizza, from which it was cut. A sector can be any size, however a sector that is half a circle (180°) is called a semicircle, while a quarter circle sector (90°) is called a quadrant.
One may also ask, what kind of triangle is a pizza slice? The Classic Triangle The most traditional way to enjoy a pizza is by having it cut into a classic triangle shape. One of the best parts about the triangle-cut pizza is the equal size of slices. A majority of slices will remain the same size and the pizza is cut down into equal parts.
Furthermore, what is a shape with curved sides called?
Any shape that can be drawn in the plane is called a plane figure. A shape with only straight sides as edges is called a polygon(POL-ee-gone). Circles and semicircles are not polygons because they have curved sides. When all the sides of a polygon are equal, it is equilateral (ee-quee-LAH-teh-roll).
Is pizza a triangle?
It's almost never a triangle. But if you're sharing it with others, it only make sense to make all the slices similar. That said, not all pizzas are circular. Sicilian pizza pies are square or rectangular.
Related Question AnswersWhy is pizza cut in triangles?
Pizza is cut into triangle slices because that is the most common way to equally divide a circle – think of a pie chart. You can also fold slices. This is particularly common in New York where pizza is sold by the slice and is often for take out food.What is a pointed oval called?
The term oval when used to describe curves in geometry is not well-defined, except in the context of projective geometry. Many distinct curves are commonly called ovals or are said to have an "oval shape". Generally, to be called an oval, a plane curve should resemble the outline of an egg or an ellipse.What is a tube shape called?
tube. A tube is a pipe shape, a cylinder with a hollow space inside. Though it's not true in the US, in London the subway is also familiarly known as the Tube.What is the shape of a pizza?
It seems that many people are genuinely curious as to why pizzas mainly come in a circular shape. Admittedly, yes, some do come in a square or rectangular shape, but most are round. The history of pizza is debatable. The word pizza was allegedly first documented in 997 AD in Gaeta, and then eventually in Italy.What is a polygon shape?
Definition of a Polygon A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons. The name tells you how many sides the shape has. For example, a triangle has three sides, and a quadrilateral has four sides.What shape is a quarter circle?
