Triangle is a polygon with the least number of sides and is also classified into six categories based on sides and angles. The names of different triangles are: Types of Quadrilaterals A quadrilateral is a four-sided, two-dimensional, closed shape. It…
Concave and Convex Polygon
The types of the polygon are:
In Mathematics, shapes define the outline or the boundary of an object. The shapes can be classified into different types based on their properties. In general, the shapes are closed by an outline or boundary, which is made up of…
In geometry, shapes define the outline or the boundary of an object. A shape is defined for an object or any external surface or boundary, apart from other properties such as colour or material type. For example, a blue ball, made up…
Q1 What is the rule to add integers? The rules to add integers are:+ and + is Sum– and – is Sum with ‘-’ sign+ and – is difference with the sign of highest value Q2 What is the rule…
Example 1: Evaluate the following: Solution: ⇒ (-1) + (-2) [Transform subtraction problems into addition problems] ⇒ (-1) + (2) [Subtract and put the sign of greater number] Hence, (-1) – ( -2) = 1 Example 2: Add -10 and…
Closure property: The difference between any two given integers results in an integer. For instance, 13 – 17 = – 4 and – 4 is an integer. In the same way, – 5 – 8 = – 13 and – 13…
The addition properties for whole numbers are valid for integers. Closure Property: The sum of any 2 integers results in an integer. For instance, 12 + 3 = 15 and 15 is an integer. In the same way, 17 + (-…
Like in addition, the subtraction of integers also has three possibilities. They are: For ease of calculation, we need to renovate subtraction problems the addition problems. There are two steps to perform this and are given below. Once the transformation is…
