In order to form a line and right angle turns (in case your quilting) sew an EVEN number of SAME size triangles.
They will form a 4 sided quadrilateral if the triangles are the same sizes.
Two right triangles, when joined together by their hypotenuses (the side opposite the right angle), will form a rectangle.
Yes. They can form a kite.
Any 2 congruent triangles joined together will form a 4 sided quadrilateral
If they are congruent right angle triangles then just join them together side by side to form a parallelogram.
there is no artificial border line...... natural line exists in the form of palk straight& gulf of manner
It can form 7 triangles
Two scalene right triangles that are congruent, that is, that have identical size and shape, if joined together to form a quadrilateral, will form a rectangle.
have 2 triangles put together to form a square, the medium triangle will go on top of the square, like a roof to a house....
Supplementary angles
The will form a rectangle.
Two angles are called suplementary angles if they form a straight angle, that is to say 180 degrees.
