Just draw a line... not a straight line, but a curvy one... Some people would draw two parallel curvy lines, with equally-spaced diagonal lines between, to represent the 'twist' of the rope.
A polygon is a closed plane figure consisting of straight lines. So a square is a polygon, a pentagon is a polygon. Just draw any closed figure with straight lines and you have a polygon.
-- Just go ahead and draw a triangle. Any triangle.-- Did you do it ? Good.-- Your triangle has three angles in it.
Let's assume the triangle has points A, B, and C. Method 1 (3 lines) Draw two lines across the triangle parallel to line segment AB. Now you have two trapezoids and one triangle. Draw another line from C to the any point on the closest of the two lines you just drew, splitting the triangle into two more triangles. Method 2 (2 lines) Draw one line across the triangle parallel to line segment AB. Now you have one trapezoid and one triangle. Draw a second line that passes through C and is perpendicular to AB, splitting the trapezoid into two trapezoids and the triangle into 2 triangles. Method 3 (3 lines) Draw one line from point C to any point on line segment AB. Then draw a line parallel to AC and one parallel to BC, but don't let them cross the line you just drew.
A polygon is a plane figure bounded by a finite number of straight lines. To enclose an area then a minimum of three straight lines are required. All triangles, not just isosceles triangles, are polygons.
An isosceles right triangle is a 45Â° 45Â° 90Â° triangle. If you know how to construct a right angle (two lines that are perpendicular), then just take a compass, with the point on the intersection of the perpendicular lines, and mark the same distance on each of the perpendicular lines, then use a straight edge to connect those two points. Or, if you have a square, you can connect two of opposite corners with a diagonal and you will have 2 triangles, both of them isosceles right triangles.
no, it is impossible
you just draw lines
No. it is the only polygon that can not have parallel lines all though any regular polygon with an odd number of lines will have no parallel lines If three points were in a straight line it could be argued that these formed a triangle with parallel sides, though really it would be just a line; or if we had a triangle with infinite height the sides would be parallel. In any other case, no.
Just draw the diagonals and you have four quarters.
Nothing, a straightedge is a ruler. Straightedge is just another name for a ruler. You can also draw straight lines with things such as the side of a folder or anything else with a flat edge.
