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.
By cutting through its diagonal and cutting off each corner parallel to its diagonal which will leave you with 2 triangles and 2 trapezoids.
Because there are 6 triangles in a hexagon, and 3 triangles in a trapezoid, there are 2 trapezoids in a hexagon.
By cutting off two of its corners which will leave you with 2 triangles and 1 pentagon.
With a pair of scissors by cutting off two off its corners leaving you with 2 triangles and 1 pentagon.
There are 2 triangles in a square so the ratio to square and triangle is 2 to 1
The formula is A=1/2bh b=base of triangle h=height of triangle A=area 1/2=divide base times height by 2
The following is a simple way to divided any triangle into n^2 congruent triangles (n > 1):Divide each side of the triangle into n equal parts,Select a pair of lines and join pairs of the above division marks with lines which will be parallel to the third side.Repeat step 2 with the other two pair of lines.
No because a triangle is only an isosceles triangle when it has 2 equal sides
No you can't
Then its not a triangle.
