Some triangles are equilateral, but not all of them. There are three types of triangles. Triangles which have three equal sides and three equal angles are called equilateral triangles. Isosceles triangles have two equal sides and two equal angles. Scalene triangles have no equal sides and no equal angles.

There are infinite amounts of quadrilaterals that have sides that aren't all equal. In regular quadrilaterals, however there are rectangles and kites that have uneven lengths of sides.
Cut it just like a pizza. Cut it from the middle top to the middle bottom and from the middle left side to the middle right side. You should have four smaller squares all of equal size. Now cut each square diagonally to make 8 triangles. All 8 triangles are the same size. -- Place two diagonals from corner to corner or the square -- this is basically slicing the square into four, equal triangular quadrants. Then slice each of those triangles in half. That makes 8 triangles of equal area.
You will either get two triangles, two rectangles, or two irregular quadrilaterals.
Yes
Not true because all quadrilaterals contain 2 triangles

By angle: a right triangle. By sides: an isosceles triangle.

Yes, it can always be divided in 2 triangles. This is because every quadrilateral has 2 diagonals. It is these diagonals that divide the quadrilateral into 2 triangles.
There are two types of quadrilaterals that are formed when two congruent equilateral triangles are joined. These shapes are rhombus and parallelogram.
If the angles of two triangles are equal the triangles are similar. AAA If you have three angles on both triangles these must be equal for the triangles to be similar. SAS If you have an angle between two sides and the length of the sides and the angle are the same on both triangles, then the triangles are similar. And SSS If you know the three sides
If you accept that the sum of the angles in a triangle is 180 degrees, then picture this. A quadrilateral shape is two triangles. If you draw a line between one pair of opposite corners in quadrilateral shape, you have two triangles that share a common side. The sum of the angles in the quadrilateral must equal the sum of the angles in the two triangles. 2 x 180 = 360
