Corresponding
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.
Line Symetry
Any symmetrical figure has two halves that match. By definition, you cannot have more than two halves of a figure.
A congruent triangle is a triangle that has the same size and shape as another triangle. This means that all corresponding sides and angles of the triangles are equal. Congruent triangles can be identified in geometric figures by comparing the lengths of their sides and the measures of their angles to see if they match up exactly.

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
To multiply with significant figures, multiply the numbers as usual and then round the answer to match the number of significant figures in the least precise number used in the calculation.
