Class 7 Maths Worksheet Lines and Angles A line is a long one-dimensional mark or a long path that goes till infinity. What is an angle? A figure known as an angle is created when two line segments or rays come together at a single vertex. The two line segments are referred to as the angle's sides. It is indicated by the letter "o" in the degree symbol. Practice Maths Worksheet I. Fill in the table with the corresponding angles  –   Sl no.

Integers - Definition and Examples - Class 7 Maths Definition of an integer: The word "integer" signifies "total" or "whole." Integers are comparable to whole numbers, with the exception that they can contain negative values. An integer is a number without a decimal or fractional element that comes from the set of negative and positive numbers that includes zero. Examples of integers -2, 10, 5, 800, and 1470 are examples of integers. Z represents a set of integers, which consists of: There are three types of integers: Zero (0) : There is no positive (or negative) integer for zero. As a result, zero is a neutral number, meaning it has no sign. Natural Numbers (Positive Integers) : Positive integers are natural numbers (also referred to as counting numbers). The denotation for these integers is Z+. The direction on the number line where positive integers lie is on the right side of 0. Negative Integers (Natural Numbers' Additive Inverse) : Negative inte

Triangles and its Angles Class 7 Maths A triangle is a closed figure made of three line segments. Triangles can be classified in 2 ways, according to angles and according to length of the sides. According to angles, there are three types of triangles – acute, right, and obtuse-angled triangle. According to length of sides, triangles can be classified as – Scalene, Isosceles, and Equilateral triangle. The types of Triangle-based on Sides are: EQUILATERAL TRIANGLE: A triangle having all the three sides of equivalent length is called an equivalent triangle. If we divide 180º by the triangle’s number of sides to determine the three angles’ measurements, we will get 60º.  Each of the equilateral triangle’s angle measures 60º. ISOSCELES TRIANGLE: A triangle having any 2 sides of equivalent length is an Isosceles triangle. The two opposite angles of equal sides are also equal in an isosceles triangle. The side that is different is located precisely between the equal
