Shapes Names List, Definition and Examples
Table of Contents
Shapes are geometric expressions that we often encounter in daily life. They consist of different sides, lines, and angles. They are formed by the union of the base on a plane at a point out of the plane or by the joining of equal parts. Knowing the meanings of shapes is useful in our daily life.
We can understand what shapes are by asking different questions. For example: “How many sides does it have, are all angles equal, or are all sides equal?” We can ask questions like.
Here are the names of some shapes:
A square is a four-sided shape formed by joining 4 straight lines. The lines in the square are all equal and come together to form 4 right angles.
Geometrically, the circle is different from the square, it has no straight lines. It consists of curves, all of which are connected to each other. In a circle, unlike other geometric shapes, there is no angle to be found.
Similar to a square, a rectangle is formed by joining four line segments. But there is an obvious difference between a square and a rectangle. The two-line segments of the rectangle are longer than the other two. These two separate lines are equal to each other. Therefore, in geometry, a rectangle is also called a long square.
A triangle consists of three connected line segments. Unlike a square, the angles in a triangle can have different measurements. They also differ from each other in shape. Triangles vary and are named as such, depending on the type of angles contained within the triangle. For example, if a triangle has a right angle, it is known as a right-angled triangle.
However, if all angles of a triangle are less than 90 degrees, it is called an acute triangle. Moreover, if one of the angles in the triangle is greater than 90 degrees, then it is known as an obtuse triangle. Finally, there is an equilateral triangle in which all angles of the triangle are 60 degrees. On the other hand, a triangle can also be named according to the types of sides it has. An isosceles triangle has two congruent sides. An equilateral triangle has three congruent sides.
