Sedangkan panjang salah satu diagonalnya, EFnya samaĭiketahui panjang sisi AD dan BC jajar genjang ABCD. Terhubung ke simpul D dan B, sehingga terdapat jajar genjang baru EBFD yangĭiagonal EF yang lebih pendek sejajar dengan sisi AD dan BC yang diketahui Titik tengah dua sisi yang berhadapan adalah E dan F Terjemahan dari bahasa Inggris ke bahasa Indonesia. Side AB and CD of the parallelogram ABCD. Length of the other diagonal BD is not equal to half the length of the other To the known side lengths AD and BC of the parallelogram ABCD. Meanwhile, the length of one of the diagonals, EF is equal Shorter diagonal EF is parallel to the sides AD and BC of the known The midpoints of two opposite sides are E and FĪre connected to vertices D and B, so there is a new parallelogram EBFD whose Thus, segment GH is midline in triangle BCE, parallel to its base BC. Similarly, point H is intersection of the diagonals of parallelogram FCDE - therefore, point H Point G is intersection of the diagonals of parallelogram ABFE - therefore, point G is Without further explanations, it should be clear to you, that ABFE and FCDE are parallelograms. They want you prove that GH is half of BC. To the sides of the given parallelogram ABCD. ![]() Green lines form parallelogram EGFH, whose diagonals EF and GH (red lines) are parallel They are connected with vertices of the parallelogram ABCD (green lines). E and F are two mid-points in opposite sides. On the Figure, you see parallelogram ABCD. It is the same as to have a map of the Treasure Island, which will lead you to the buried treasure. In this problem, the key step is to make right plot, which will lead you to correct proof. Is equal to half the length of the other side of the parallelogram. Is equal to a known side length of the parallelogram and the length of the other ![]() Meanwhile, the length of one of the diagonals The vertices, so there is a new parallelogram whose diagonals are parallel to the The midpoints of two opposite sides are connected to Terjemahan dari bahasa Indonesia ke bahasa Inggris: Question 1204115: please solve these problems with steps: | ~(T v W) Assumption for Indirect Proofġ8. Refer to these rules of inference and replacementĪnswer by Edwin McCravy(19482) ( Show Source):Ĥ. Here is a review of various truth table rules Notice that we do not have a situation where all premises are true but the conclusion is false. There's nothing really special about the r. In fact, we can replace r with any other logical statement. We then know that p isn't the case since ~p is, so q must be the case. ![]() Using ~p and p v q, we find that q comes out of that. If ~p ^ r is the case then ~p is the case and r is also the case. You can put this solution on YOUR website!
