How A pentagon can be divided into how many triangles by drawing all of the diagonals from 1 vertex?
Three triangles
How do you divide a rectangle into 4 identical triangles?
Divide the rectangle in half, so you have two squares. Then cut each of these squares in half by drawing a straight line from the top left hand corner to the bottom right hand corner. Then you'll have four right angle triangles. * * * * * A rectangle, divided in half need not give a square. Try it with an A4 sheet of paper. A much simpler answer is to draw the two diagonals.
Why drawing a diagonal on any parsllelogram will always result in two congruent triangles?
Well a parallelogram is a 4 sided shape with 2 pairs of parallel lines, hence PARALLELogram. That's the reason, because there are two pairs of parallel lines.
Octagon can be divided into triangles by drawing how many straight lines?
yes
What will be the ratio of circles to triangles in a drawing showing 4 circles and 7 triangles?
4/(7) = 4/7 is the ratio of circles to triangles. Some prefer to express this as 4:7.
Does Drawing one diagonal trapezoid creates two congruent triangles?
No, in general, it does not.
Drawing one diagonal trapezoid creates two congruent triangles?
The answer is: usually not.
Does drawing one diagonal in a trapezoid create two congruent triangles?
Yes It always does because of how a trapezoid is shaped.
The sum of interior angles of a square is?
360 degrees. Same for any other rectangle, rhombus, parallelogram, or convex quadrilateral. The reason is that any quadrilateral can be divided into two triangles by drawing a diagonal and the sum of the angles of each triangle is 180 degrees.
The sum of the interior angle measures of an octagon?
To find interior angle measurements, you must divide the shape into triangles by drawing diagonal lines. The diagonal lines draw triangles, and the interior angle measure of triangles are always 180 degrees. The sum of interior angles of an octagon is 1080 degrees. How ever many triangles you have, multiply it by 180. See octagons in the link for more help,
Why is drawing the diagonals of a parallelogram help full in proving many of the parallelograms properties?
It is helpful (not help full) because the two triangles formed by either diagonal are congruent.
Why is the sum of the interior angles of a quadrilateral 360 degrees?
This result follows from the theorem that the sum of the angles of a triangle is 180 degrees. Drawing a diagonal in the quadrilateral splits it into two triangles and the angles of the triangles together combine to form the angles of the quadrilateral.
What is the width a rectangle?
That is decided by the person proposing or drawing the rectangle.
