yes it is true
An equilateral triangle and an isosceles triangle would both have lines of symmetry that would split it into two triangles.
A diagonal bisecting a square creates two identical right triangles. The diagonal is the hypotenuse of a right triangles, so its length is the square root of the sums of the squares on the opposite two sides.
This is known as the Sierpinski triangle.

if you draw a line from one corner of a rectangle to the opposite it creates two triangles
A right angle triangle or an isosceles triangle.
An equilateral triangle and an isosceles triangle would both have lines of symmetry that would split it into two triangles.
Yes, the diagonals of an isosceles triangle are congruent. This is because an isosceles triangle has two sides that are equal in length, which creates two congruent triangles when the diagonals are drawn.
No, in general, it does not.
The answer is: usually not.
The diagonal of a parallelogram divides it into two congruent triangles. This is because the diagonal creates two pairs of congruent triangles by dividing the parallelogram into two equal halves.
Oh, dude, so like, an isosceles trapezoid can totally be divided into 4 equal parts by drawing two diagonals from the top vertices to the bottom base. This creates four triangles, and since the trapezoid is isosceles, the diagonals will be equal in length, dividing the trapezoid into four equal parts. It's like magic, but with math!
A diagonal bisecting a square creates two identical right triangles. The diagonal is the hypotenuse of a right triangles, so its length is the square root of the sums of the squares on the opposite two sides.
As you can see, this square is made up of two triangles. The line drawn down the middle, from corner to corner, is the line you are asking about, that creates the "two things" or the two triangles on either side of it.
This is known as the Sierpinski triangle.
