EXERCISE 8.1 | TS-CLASS 8TH-MATHS-CHAPTER 8-EXPLORING GEOMETRICAL FIGURES ||

Full exercise 8.1 has been solved in an easy and simple manner. It includes solution of questions from Question 1 to 9. Questions: 00:00 Q1. Name five pairs of congruent objects, you use daily. 02:02 Q2. (a) Draw two congruent figures. Are they similar? explain (b) Take two similar shapes. If you slide rotate or flip one of them, does the similarity remain? 05:27 Q3. If ΔABC "≅" ΔNMO, name the congruent sides and angles. 06:51 Q4. State whether the following statements are true. Explain with reason. 12:18 Q5. Draw a polygon on a square dot sheet. Also draw congruent figures in different directions and mirror image of it. 14:20 Q6. Using a square dot sheet or a graph sheet draw a rectangle and construct a similar figure. Find the perimeter and areas of both and compare their ratios with the ratio of their corresponding sides. 17:17 Q7. 7 pillars are used to hold a slant iron gudder as shown in the figure. If the distance between every two pillars is 1m and height of the last piller is 10.5m. find the height of pillar. 21:42 Q8. Standing at 5m apart from a vertical pole of height 3m. Sudha observed a building at the back of the piller that tip of the pillar is in the line with the top of the building. If the distance between pillar and building is 10m, estimate the height of the building. [Here height of Sudha is neglected] 24:03 Q9. Draw a quadrilateral of any measurements. Construct a dilation of scale factor 3. Measure their corresponding sides and verify whether they are similar.
