How do you find the midpoint of segment gf if the quadrilateral EFGH has coordinates E 2b b F 3b 2b G b 0 and H 0 0?
Each coordinate of the midpoint of a line segment is the average of the corresponding
coordinates of the end points.
'x' of the midpoint = average of 'x' of the endpoints
'y' of the midpoint = average of 'y' of the endpoints
For segment GF, you only need the coordinates of 'G' and 'F'.
G . . . (b, 0)
F . . . (3b, 2b)
'x' of the midpoint = 1/2 (b + 3b) = 1/2 (4b) = 2b
'y' of the midpoint = 1/2 (0 + 2b) = 1/2 (2b) = b
Coordinates of the midpoint . . . (2b, b)
What else can I help you with?
A series of transformations maps EFGH onto its image. Determine the series of transformations that maps EFGH onto its image. In your final answer include all of your calculations.?
To determine the series of transformations that maps quadrilateral EFGH onto its image, we need the coordinates of the vertices of EFGH and its image. Typically, transformations can include translations, rotations, reflections, and dilations. For example, if EFGH is translated 3 units right and 2 units up, the new coordinates of its vertices would be calculated by adding (3, 2) to each vertex's coordinates. If further transformations are needed, such as a rotation of 90 degrees counterclockwise around the origin, the new coordinates can be calculated using the rotation matrix. Please provide the coordinates for precise calculations.
Polygons abcd and efgh are similar. find the perimeter of efgh?
To find the perimeter of polygon efgh, you need the ratio of similarity between polygons abcd and efgh, as well as the perimeter of polygon abcd. Once you have the perimeter of abcd, multiply it by the ratio to obtain the perimeter of efgh. If the ratio is not provided, it cannot be determined.
Is it true that if a line is parallel to a plane then any plane containing that line is always parallel to the given plane?
No. A line can be contained by many, many planes, Picture this, A rectangle with corners - going clockwise - A, B, C and D is the screen of your computer. This is a plane figure. 1 inch away from it a line runs from A1 to C1. The line is parallel to the plane. Now, take a sheet of paper with corners E, F, G and H, and place corner E at corner A of the screen, and place corner F at corner C of the screen. The Line AI is now 'contained' in the plane EFGH. and EFGH is perpendicular to ABCD.
Is it true if a line is parallel to plane it is parallel to any line in the plane?
If your definition of parallel lines is that they never meet, then the answer is yes. If, however, the definition is that they remain equidistant from one another at all points, then, in my opinion, the answer is no. It is difficult to explain the second without recourse to diagrams which are very difficult to manage on this site. So consider a cube with vertices ABCD forming the top face and EFGH (in corresponding order) forming the bottom face. Now AB is parallel to the bottom plane - EFGH. And AB is clearly parallel to EF and any line parallel to EF. But is AB parallel lines such as FG? True, they will never meet but the distance between them increases as you move away from BF - ie they are not the same distance apart. Incidentally, Euclid's parallel postulate was phrased in a very different way from the one most mathematicians come across it. That version is a much later equivalent statement.
How can you form six four person teams out of eight players so that in three matches all players will be teamed with everyone in the group at least once?
One possible combination is ABCD v EFGH ABEF v CDGH ABGH v CDEF This has been worked with people staying in pairs. So that at different times AB are partnered with CD, EF and GH and the same applies to the other three pairs. There are many more combinations where constant pairings are not important.

Given the vertices E-2 -1 F-4 3 G1 5 and H3 1 Determine the best classification for this quadrilateral?
Vertices: E (-2, -1); F (-4, 3); G (1, 5); and H (3, 1).Plot these points in a coordinate system and connect them. The quadrilateral EFGH is formed.The slope of the line where the side EF lies is -2.[(3 - -1)/(-4 - -2)] = 4/-2 = -2The slope of the line where the side HG lies is -2.[(5 - 1)/(1 - 3)] = 4/-2 = -2Thus the opposite sides EF and HG of the quadrilateral EFGH are parallel.The slope of the line where the side EH lies is 2/5.[(1 - -1)/(3 - -2)] = 2/5The slope of the line where the side FG lies is 2/5.[(5 - 3)/(1 - -4)] = 2/5Thus the opposite sides EH and FG of the quadrilateral EFGH are parallel.Since any of the slopes is not a negative reciprocal of the others, then the two adjacent sides are not perpendicular. And if we look at the diagram, we clearly see that this quadrilateral can be a parallelogram.The length of the side EF is square root of 20.Square root of [(5 - 1)^2 + (1 - 3)^2] = Square root of [4^2 + (-2)^2] = Square root of 20.The length of the side HG is square root of 20.Square root of [(3 - -1)^2 + (-4 - -2)^2] = Square root of [4^2 + (-2)^2] = Square root of 20.Thus, the opposite sides EF and HG of the quadrilateral EFGH are congruent.Two other parallel sides, EH and FG, must be congruent also, since they intersect two other parallel lines (their length is equal to square root of 29).So we verified that the quadrilateral EFGH is a parallelogram.
