Because if you take a triangle and double the length of each side, you get a much bigger triangle which is therefore not congruent (they do not match in every respect, even though the angles are replicated). In this case they are called "similar".
Any two corresponding sides in two similar figures have a common ratio called the scale factor. Since the figures are similar, the ratios of the lengths of corresponding sides of the figures are equal. 1. Match a side of both figures, 2. write the proportions 3. substitute the values 4. Write the cross product 5. Divide both sides by a common factor 6. simplify 7. Convert improper fraction into mixed number
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.

Any symmetrical figure has two halves that match. By definition, you cannot have more than two halves of a figure.

A trapezoid will always have two parallel sides. However, it will not necessarily have two congruent sides. The only way it will have two congruent sides is if the angles at the base match.

When multiplying numbers with significant figures, round the final answer to match the number with the least significant figures in the original numbers.
Two triangles are congruent if the six elements of one triangle (three sides and three angles) are equal to the six elements of the second triangle and the two triangles have a scale factor of 1. However, in four special cases it is only necessary to match three elements to prove that two triangles are congruent. The matching of four elements is sometimes necessary, and the matching of five elements would put the matter beyond any doubt.
cut out the polygon and fold the two sides onto each other.if the sides match up, you can assume its congruent

When dividing numbers, the result should have the same number of significant figures as the number with the fewest significant figures in the calculation. Round the final answer to match the least number of significant figures in the original numbers.
