Length of AB? EXERCISE 14.51. Draw AB of length 7.3 cm and find its axis of symmetry.mendicu |

Answer» Let's first draw a line segment of length 7.3 cm . 1) Draw a line l, mark POINT A on it. 2) Since length is 7.3 cm, we measure 7.3 cm using ruler and compass. 3) Now keeping compass opened the same length, we keep pointed end at point A and draw an arc on line l. So, the required line segment is AB = 7.3 cm . Now, we need to find its axis of symmetry. 1) Given a line segment AB. 2) Now with A as centre, and radius more than half AB, draw an arc on top and BOTTOM of AB. 3) Now with B as centre, and same radius, draw an arc on top and bottom of AB. 4) Where the two arcs intersect above AB is point C and where the two arcs intersect below AB is point D. Join CD. CD is the line of symmetry of line segment AB.Step-by-step explanation: |
