CHAPTER 9: GEOMETRICAL FIGURES
(1) 09 GEOMETRICAL FIGURES GEOMETRICAL FIGURES  INTRODUCTION Geometrical shapes are used for the construction of the geometrical figures. The basic geometrical figures are, line, line segments, angles, etc. This chapter includes the identification of the basic geometrical shapes. Geometrical Figures Line Let's see the lines given below: Example: Give the name of all slant lines from the figure given below.
(2) 09 GEOMETRICAL FIGURES (a) AD and BC (b) AB and BC (c) AB and AD (d) All the above (e) None of these Answer- (a) Question: 1. Which one of the following is correct about the line? (a) A straight line is measured by ruler. (b) A straight line cannot be measured by ruler. (c) A straight line is measured in grams, (d) All the above (e) None of these 2. Name the line showing in picture.
(3) 09 GEOMETRICAL FIGURES Answer- 1: (a) Note: We use ruler to measure a straight line. 2: Angle An angle is formed at the meeting point of two lines or an angle is formed when two lines meet. The point where two lines meet is called vertex. See the figures given below: Example:
