Understanding Elementary Shapes
Mathematics Solutions from Chapter -1 - Understanding Elementary Shapes
This chapter describes various geometrical shapes and their identification. It further explains how to measure line segments and angles using geometrical instruments such as divider, protractor, etc.
Practice Other Topics from Understanding Elementary Shapes
This topic describes that a line segment is a particular part of a line with a definite measurement that connects two points. We can measure a line with the help of a divider and a ruler by placing the end point of the segment on the zero mark on the ruler.
This topic discusses that angle is the portion between two intersecting lines. An angle can be measured with a protector. It is a figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.
This topic explains that if two lines are placed in such a way that one of them cross pass another one at 90°, the lines are said to be intersecting lines. Squares and rectangles always have four right angles
In this topic, we will learn the different types of triangles based on the length of their sides and angle. It explains there are different types of triangles based on their angles, such as acute-angled, obtuse-angled, and right-angled triangles.
In this topic, we will learn about quadrilaterals, which is a figure that has four sides and four angles. Square, rectangle etc. are quadrilaterals. The different quadrilaterals are also discussed in this topic.
In this topic, we will discuss polygons. A polygon is a closed figure that has more than three sides. Polygons are named according to the number of sides and angles they have. For example, triangle, rectangle, etc.
In this topic, we will learn different three-dimensional shapes and their properties. It states that any geometrical figure that has length, breadth and height is a three-dimensional shape like any object in the real world.
