A quantity that is cubed retains its original sign: if it starts out positive, it remains positive and if it starts out negative, it remains negative.

Decimals

tenths digit is the first digit to the right of the decimal point.

Similar Triangles

Triangles are defined as similar if all their corresponding angles are equal or if the lengths of their corresponding sides have the same ratios.

First, recall that in a right triangle, the two shorter sides intersect at the right angle.

if two similar figures have lengths in a given ratio (say A:B), then their areas will have a ratio that is the square of this length ratio (i.e.,A2:B2). Conversely, if the areas are in a given ratio, then the lengths will be in the square root of that ratio. ( Look at MGMAT CAT 4. q 19) Excellent example.
