The <em><u>correct answer</u></em> is:

Reflectional symmetry

Explanation:

Rotational symmetry is when a figure can be rotated less than 360° and be in the original orientation.  This figure cannot be rotated less than one full turn and look the same, so it has no rotational symmetry.

Reflectional symmetry is when a figure can be folded in half through some line.  This figure can be folded in half vertically, so it has reflectional symmetry.

What is the supplementary and complementary angles of 48 degrees?
Nostrana [21]

-- Supplementary angles add up to 180 degrees.
48 + S = 180
        S = 180 - 48 = <em>132 degrees</em>

-- Complementary angles add up to 90 degrees.
48 + C = 90
        C = 90 - 48 = <em>42 degrees</em>

a rectangle measures by 3 cm by 4 cm. a rectangle similar to the first measures 12 cm by 16 cm. find the ratio of the areas of r
kumpel [21]
The side that measures 12 cm corresponds to the side that measures 3 cm.
The side that measures 16 cm corresponds to the side that measures 4 cm.
The ratio of the side lengths is (12 cm)/(3 cm) = (16 cm)/(4 cm) = 4

Now let's calculate the two areas.

For the 3 cm by 4 cm rectangle:
A = LW = 3 cm * 4 cm = 12 cm^2

For the 12 cm by 16 cm rectangle:
A = LW = 12 cm * 16 cm = 192 cm^2

The ratio of the areas is (192 cm^2)/(12 cm^2) = 16

The ratio of the areas is 16.
The ratio of side lengths is 4.
Notice that 16 = 4^2.
The ratio of the areas is the square of the ratio of the side lengths.
