give me an example for all of them
rectangle – a four-sided shape of two sets of opposite sides that are of congruent length with four right angles
composition – the creation of a shape around a central shape
hypotenuse – the side of a right triangle that is across from the right angle
right triangle – a triangle with a right angle
An example of a right triangle would be a triangle with one angle measuring 90 degrees and the other two angles measuring less than 90 degrees. The sides of a right triangle are related by the Pythagorean theorem, where the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
An example of a rectangle would be a piece of paper with four right angles and opposite sides that are of equal length.
An example of composition would be creating a hexagon by surrounding a central square with six equilateral triangles.
