1 00:00:00,580 --> 00:00:07,570 Let's do this question, ABCDs, a quadrilateral in which is equal to five centimeter and Krazy Glue 2 00:00:07,570 --> 00:00:11,840 eight centimeter, the sum of the angle E and D is 180 degrees. 3 00:00:12,190 --> 00:00:14,020 What is the name of this quadrilaterals? 4 00:00:14,050 --> 00:00:14,490 All right. 5 00:00:14,740 --> 00:00:16,120 This is a fundamental question. 6 00:00:16,360 --> 00:00:18,820 It just helps you to solidify your base. 7 00:00:19,090 --> 00:00:22,040 Now, pause the video, give it a thought, and then let's do it together. 8 00:00:22,300 --> 00:00:22,770 All right. 9 00:00:22,780 --> 00:00:23,690 Let's do it together. 10 00:00:23,890 --> 00:00:30,610 We have ABCDE and it's given ABS equal to five centimeter and CDs equal to eight centimeters. 11 00:00:30,730 --> 00:00:34,690 It's also given that angle, eight plus angle is equal to 180 degree. 12 00:00:34,840 --> 00:00:35,230 Right. 13 00:00:35,410 --> 00:00:39,930 So from this we can understand that abs parallel to D.C., right. 14 00:00:40,060 --> 00:00:45,010 Because the consecutive indeed triangles are supplementary and we have seen that. 15 00:00:45,010 --> 00:00:47,710 If that is true, then the two lines will be parallel. 16 00:00:47,890 --> 00:00:55,030 Now, therefore, the answer to this question is tropism y because we have seen that AB is parallel 17 00:00:55,030 --> 00:00:57,530 to city and the length is not equal. 18 00:00:57,550 --> 00:00:58,450 So this is five. 19 00:00:58,720 --> 00:00:59,530 This is longer. 20 00:00:59,530 --> 00:01:00,170 This is eight. 21 00:01:00,310 --> 00:01:02,330 So these two sides cannot be parallel. 22 00:01:02,500 --> 00:01:04,210 Therefore, it's not a program. 23 00:01:04,360 --> 00:01:04,720 Right. 24 00:01:04,900 --> 00:01:06,250 And it's not a rhombus. 25 00:01:06,250 --> 00:01:06,790 We'll see that. 26 00:01:06,790 --> 00:01:09,300 A rhombus is also about kilogramme in a future video. 27 00:01:09,550 --> 00:01:11,940 And hence this is a tropism. 28 00:01:11,950 --> 00:01:13,650 The correct answer is option B. 29 00:01:13,990 --> 00:01:14,380 All right. 30 00:01:14,530 --> 00:01:19,550 Now, let's do the second question, but which of the following diagonals bisect each other? 31 00:01:19,750 --> 00:01:21,110 So what's the correct answer? 32 00:01:21,340 --> 00:01:25,990 We know that in the case of a parallelogram, the diagonals bisect each other. 33 00:01:25,990 --> 00:01:26,350 Right. 34 00:01:27,070 --> 00:01:33,400 Therefore, the correct answer is option E, because the square is also a program we have seen over 35 00:01:33,400 --> 00:01:39,250 here that trapezius is not a program and inequality is also not a problem. 36 00:01:39,400 --> 00:01:44,500 And in a future video, we will see that a kite is also not a program. 37 00:01:44,500 --> 00:01:47,750 Therefore, the correct answer is option E, that is a square. 38 00:01:48,070 --> 00:01:48,480 All right. 39 00:01:48,700 --> 00:01:50,150 What about the next question? 40 00:01:50,470 --> 00:01:53,830 Well, which of the following figures or angles are equal? 41 00:01:55,250 --> 00:01:57,590 The correct answer to this will be. 42 00:01:58,970 --> 00:02:05,120 Option eight, that is a rectangle, right, because each angle is equal to 90 degrees in the case of 43 00:02:05,120 --> 00:02:06,110 a rectangle. 44 00:02:06,500 --> 00:02:08,150 So option is the correct answer. 45 00:02:08,530 --> 00:02:12,050 Over here, you can see in the case of a trapezius, every angle is not equal. 46 00:02:12,210 --> 00:02:13,620 So that's not the answer. 47 00:02:13,650 --> 00:02:14,960 Right and wrong. 48 00:02:14,960 --> 00:02:17,600 But also you will see that all angles are not equal. 49 00:02:17,810 --> 00:02:21,730 And same in the case of a kite, although you will see that all angles are not equal. 50 00:02:21,920 --> 00:02:29,930 The only four sided polygons in which all angles are equal are rectangles and squares where each angle 51 00:02:29,930 --> 00:02:31,670 is equal to 90 degrees.
