1 00:00:00,620 --> 00:00:04,560 Let's do this question asks parallel to Eddie. 2 00:00:04,840 --> 00:00:12,050 All right, and it's given that a B is equal to B.S. So these two sides are equal and that's equal. 3 00:00:12,050 --> 00:00:13,340 Do it all right. 4 00:00:13,490 --> 00:00:15,830 And if is equal to F.P.. 5 00:00:15,860 --> 00:00:17,330 So these two sides are equal. 6 00:00:17,330 --> 00:00:21,800 If it's the midpoint of each find the ratio of any of EDC. 7 00:00:21,800 --> 00:00:26,060 That's this triangle over here to the area of FGB. 8 00:00:26,060 --> 00:00:27,420 That's this triangle over here. 9 00:00:27,620 --> 00:00:28,120 All right. 10 00:00:28,340 --> 00:00:31,770 Pause the video, give it a try and then let's do it together. 11 00:00:32,390 --> 00:00:32,810 All right. 12 00:00:32,810 --> 00:00:33,260 We're back. 13 00:00:33,290 --> 00:00:34,280 Let's do it together. 14 00:00:34,430 --> 00:00:35,850 I hope you have given it a try. 15 00:00:36,170 --> 00:00:39,470 Now let's join point B to E and Andy. 16 00:00:40,460 --> 00:00:47,330 All right, now let's start marking all the information that's already been given to us. 17 00:00:47,630 --> 00:00:49,250 All right, let me do it again over here. 18 00:00:49,670 --> 00:00:58,190 We know that Eddie and ACOR parallel, ABC and Eddie are equal and if is equal to FEMA. 19 00:00:58,340 --> 00:01:00,380 But that's the information that we have. 20 00:01:00,650 --> 00:01:01,650 All right, now. 21 00:01:01,820 --> 00:01:05,390 We have joined Ebbe and Beatty right now. 22 00:01:05,390 --> 00:01:10,490 In this way, we have divided this ship into six equal areas. 23 00:01:10,790 --> 00:01:11,090 Right. 24 00:01:11,300 --> 00:01:12,560 We had discussed this before. 25 00:01:12,710 --> 00:01:16,860 In this way, we have divided this ship into six equal areas. 26 00:01:17,180 --> 00:01:20,990 Now we need to find the ratio of any of EDC. 27 00:01:21,260 --> 00:01:22,490 That's this part. 28 00:01:22,610 --> 00:01:25,730 So for EDC, you have to pick one two. 29 00:01:25,740 --> 00:01:27,270 You're taking two parts, right? 30 00:01:27,440 --> 00:01:28,310 That's this part. 31 00:01:28,310 --> 00:01:30,140 And this part two from EDC. 32 00:01:30,410 --> 00:01:38,120 Now to find the area of F, a, B, you're just taking one part right there for the answer to this question 33 00:01:38,300 --> 00:01:40,960 is to divide it by one. 34 00:01:40,970 --> 00:01:41,330 Right. 35 00:01:41,540 --> 00:01:44,260 This is two and this is one that's about it. 36 00:01:44,270 --> 00:01:45,320 That is the answer. 37 00:01:45,320 --> 00:01:46,290 Wasn't that fast. 38 00:01:46,610 --> 00:01:51,800 Now, over here you can see that ECB is a parallelogram, right? 39 00:01:52,580 --> 00:01:54,120 Let's try to understand it now. 40 00:01:54,270 --> 00:01:57,140 Now, in the exam, you should have moved on to the next question. 41 00:01:57,350 --> 00:01:58,100 Just marking. 42 00:01:58,100 --> 00:01:59,090 It has to buy one. 43 00:01:59,330 --> 00:01:59,780 All right. 44 00:01:59,960 --> 00:02:01,960 Now, DCB is a battleground. 45 00:02:02,360 --> 00:02:02,950 All right. 46 00:02:03,080 --> 00:02:09,500 So area of triangle E, D, C, that's this part is equal to area of EBC. 47 00:02:11,020 --> 00:02:11,320 Right. 48 00:02:12,270 --> 00:02:17,550 All right, so these two are equal now you can see that these two are congruent, right? 49 00:02:17,560 --> 00:02:18,880 We have proved that before. 50 00:02:19,070 --> 00:02:22,340 Therefore, these two areas are also equal. 51 00:02:22,480 --> 00:02:29,590 Now, if the area of DCB is taken as a then these two will be of area Ebeye to. 52 00:02:31,100 --> 00:02:37,580 All right, now you can see that area of E. The beat, that's this part over here. 53 00:02:38,520 --> 00:02:47,850 That is also equal to EBITA because this area and DBC is also equal right to area of EDB is also equal 54 00:02:47,850 --> 00:02:48,840 to EBITA. 55 00:02:49,260 --> 00:02:56,610 Now you can see that Eddy, be it this part over here also gives you Eppalock. 56 00:02:56,910 --> 00:02:57,260 Right. 57 00:02:57,400 --> 00:02:59,340 But this part also is a program. 58 00:02:59,610 --> 00:03:06,050 So area of E, B, that is this part over here is equal to area of DB. 59 00:03:06,180 --> 00:03:07,530 That is this part over here. 60 00:03:08,690 --> 00:03:09,910 Let me write that over here. 61 00:03:10,300 --> 00:03:19,940 These two areas are equal, and if we take the area of EDV as a then each of these is equal to by two. 62 00:03:20,510 --> 00:03:20,940 All right. 63 00:03:21,350 --> 00:03:24,530 Now, why have we taken the area of EDB? 64 00:03:24,530 --> 00:03:27,590 Is it as well as the area of Iraq? 65 00:03:27,680 --> 00:03:29,070 B, as A right. 66 00:03:29,240 --> 00:03:30,760 What is the area of a program? 67 00:03:30,770 --> 00:03:32,410 It's based in the height. 68 00:03:32,420 --> 00:03:32,740 Right. 69 00:03:32,930 --> 00:03:37,310 You will see that these two have the same base that's over here. 70 00:03:37,310 --> 00:03:38,480 It's Abian over here. 71 00:03:38,480 --> 00:03:39,110 It's busy. 72 00:03:39,230 --> 00:03:41,210 And we know that they are of equal length. 73 00:03:41,450 --> 00:03:43,910 And these are between two parallel lines. 74 00:03:44,060 --> 00:03:46,470 So the height of these two also will be the same. 75 00:03:46,700 --> 00:03:49,490 That's why both of them are of equal area. 76 00:03:49,560 --> 00:03:49,940 All right. 77 00:03:50,150 --> 00:03:50,910 Now what? 78 00:03:50,930 --> 00:03:57,140 Over here you can see that the area of F a B is equal to half of EBITA. 79 00:03:57,410 --> 00:04:00,290 Right, because these two triangles are congruent. 80 00:04:00,500 --> 00:04:05,150 Therefore, the area of F a B is equal to Ebeye for now. 81 00:04:05,150 --> 00:04:12,020 Having established these things, you can find that the required ratio is Ebeye two. 82 00:04:12,020 --> 00:04:13,310 That's LDC, right. 83 00:04:13,520 --> 00:04:22,280 EDC is equal to EBI two and F maybe that's it by four so ebi to buy by four and that gives you the answer 84 00:04:22,280 --> 00:04:24,770 as to by one or two is to one. 85 00:04:24,860 --> 00:04:31,580 And that's the same thing that we got within two or five seconds in the beginning itself, just using 86 00:04:31,760 --> 00:04:33,710 graphical division method.
