A square and rectangle both have congruent triangles in them.
opposite sides are congruent corresponding parts of congruent triangles are congruent(apex)
Yes. You can show this by SAS of two right triangles. Consider rectangle ABCD. AD and BC are the same length and AC and BD are the same length because opposite sides are congruent. The angles ADC and BCD are congruent since it is a rectangle and the angles are right angles. So the triangles ADC and BCD are congruent and their hypotenuses (the diagonals of the rectangles) are congruent.
prove any two adjacent triangles as congruent
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.
A square and rectangle both have congruent triangles in them.
triangles and straight lines you can get on decomposing a rectangle.
A rectangle has two pairs of congruent (meaning identical) sides.If, however, you drew two lines diagonally from corner to corner, you would have two pairs of congruent triangles within the rectangle.
I think a rectangle is NOT made up of congruent shapes because it only does not have triangles.
opposite sides are congruent corresponding parts of congruent triangles are congruent(apex)
If the triangles are congruent and you match the hypotenera the right way, you can get a rectangle. If the triangles are not congruent, you can't even necessarily get a quadrilateral.
