To divide a rectangle into 7 parts using 3 lines:
Use 2 lines to draw two diagonals. Use the third line to draw a parallel line to any of the sides but not passing through the centre. This will create 7 parts in the rectangle.

How many lines of symmetry do squares have?
The square has four lines of symmetry. The rectangle has only two, as it can be folded in half horizontally or vertically: students should be encouraged to try to fold the rectangle in half diagonally to see why this does not work.
How do you prove the formula for the area of a triangle?
Easiest wayDraw a three inch by three inch square. add lines at one inch marks to form a small grid. draw line diagonally across to form two triangles. count the number of squares in one triangle (remember the squares with the diagonal line are only half a square)Did you get 4 1/2?A X B divided by two 3 X 3= 9 / 2 = 4.5To arrive to the forumla for area of triangle, lets look at the area of square and rectanlge first: Area of square: side x side Area of rectangle: length x width Notice that the formulas for area of square and rectangle is very similar. The squre is a special case only, so there is not much difference. Let's take the special case first- area of square: Area= side x side If I want to find the area of a triangle from this square, you have to divide the square in half diagonally. This means: (side x side)/2 = area of triangle Let's take a look at retangle now: Area of rectangle: length x width Similarly like the square, you divide the rectangle diagonally by half. This means: (length x width)/2 Conclusion: Thus, area of triangle= (base x height)/2 The base can be considered as one of the sides of the rectangle/square, and the height can be considered as the other side of the rectangle/square. THE FORMULA OF TRIANGLE COMES FROM HALF THE AREA OF RECTANGLE/SQUARE! Visit quickanswerz.com for more math help and tutoring!Area is measured in square units. If we are given a region we divide the region into unit squares.Then we count the number squares, which is the area of the region.Consider a rectangle of length 10 units and width 5 units.The area of the rectangle is 50 square units.It is because we can divide the rectangle into 10 equal parts along the length.Similarly, we can divide the rectangle into 5 equal parts along the width. Now we have divided the entire rectangle into unit squares.If we count the number of squares we get 50 unit squares.We get this by multiplying the length and the width. Area = Length*Width square units.This is the same for a parallelogram too.Area of a parallelogram is base * height square unitsThis is how the concept of area has come.We can find the area of the triangle also.A rectangle or a parallelogram can be divided into two equal triangles by a diagonal.Half of the area of the rectangle(or parallelogram) gives the area of the triangle.In fact, we can extend any triangle into an parallelogram.So, we get the formula, area of a triangle = (base* height)/2 square units.Source: www.icoachmath.com
What is the Golden Rectangle?
The Golden Rectangle is a geometrical figure whose side lengths are in the golden ratio. It can be made with only a compass and a straight edge.
How do you divide a rectangle into 8 parts using only 3 lines?
the answer is .....you can't .You can only divide it into 6 parts NOT 8 PARTS.
How do you divide a rectangle into 8 equal parts using only 3 lines?

How do you divide a rectangle into 7 equal parts with 3 lines only?
To divide a rectangle into 7 parts using 3 lines: Use 2 lines to draw two diagonals. Use the third line to draw a parallel line to any of the sides but not passing through the centre
Lines of symmetry for a rectangle?
There are only two lines of symmetry. Divide either of the two opposite sides of the rectangle in half and join these two points.
Can you divide a square in 2 equal parts in 9 different ways?
Yes you can, but you have to use zig zag lines. Using straight lines there are only four ways to divide a square into two equal parts (along the lines of symmetry).
How do you divide a circle into eight parts using only three lines?
Draw two diameter lines, then draw a circle inside the circle.
Why is a trapezoid never a rectangle?
A rectangle has 2 pairs parallel lines and a trapezoid can only have 1 pair of parallel lines.
Quadrilateral with 4 right angles and 4 lines of symmerty?
A quadrilateral with 4 right angles can only be a rectangle or a square. A rectangle has only two lines of symmetry - the lines joining the midpoints of its opposite sides. So the answer cannot be a rectangle. A square has the same lines of symmetry as a rectangle, plus the two diagonals - 4 lines in all.
Does a square or rectangle has more lines of symmetry?
They both have the same amount of lines of symmetry. * * * * * Not true. A square has four lines of symmetry, a rectangle only two.
WHAT IS 1 WAY A SQUARE AND RECTANGLE ARE DIFFERENT?
A square has 4 lines of symmetry whereas a rectangle has only 2 lines of symmetry.
How is a rectangle and a trapezoid different?
a rectangle is a shape that has two sets of parallel lines a trapezoid only has to have one set of parallel lines
Does a rectangle have 4 lines of symmetry?
No it has only 2
