The perimeter of a polygon is the measure of the distance around the polygon.
Circumference is the distance around or perimeter of a circle.
The area of a closed curve is the number of nonoverlapping square units required to fill the region enclosed by the curve.
The perimeter of a square whose side measures x is 4 times x (P = 4x)
The area of a square whose side is "x", is side times side (A = x^2).
The perimeter of a rectangle is the sum of twice the length and twice the width [P = 2l + 2w, or
P = 2(l + w)]. Is the formula for perimeter of a rectangle.
A rectangle's area is the product of the length and the width (A = lw).
The value of pi is the ratio of the circumference of a circle to its diameter.
The ratio of the circumference to the diameter of a circle is a constant value, pi.
The fractional approximation of pi is 22/7 .
The decimal approximation of pi is 3.14.
The circumference of a circle is computed using or d*pi or 2pi*r , where d is the diameter and r is the radius of the circle.
The area of a circle is computed using the formula, pi*r^2 , where r is the radius of the circle.
The surface area of a rectangular prism is the sum of the areas of all six faces.
The volume of a rectangular prism is computed by multiplying the area of the base, B, (length x width) by the height of the prism.
1 inch is about 2.5 centimeters.
1 foot is about 30 centimeters.
1 meter is a little longer than a yard, or about 40 inches.
1 mile is slightly farther than 1.5 kilometers.
1 kilometer is slightly farther than half a mile.
1 ounce is about 28 grams.
1 nickel has the mass of about 5 grams.
1 kilogram is a little more than 2 pounds.
1 quart is a little less than 1 liter.
1 liter is a little more than 1 quart.
Water freezes at 0°C and 32°F.
Water boils at 100°C and 212°F.
Normal body temperature is about 37°C and 98°F.
Room temperature is about 20°C and 70°F
Congruent figures have exactly the same size and the same shape.
Noncongruent figures may have the same shape but not the same size.
The corresponding angles of congruent polygons have the same measure, and the corresponding sides of congruent polygons have the same measure.
The determination of the congruence or noncongruence of two figures can be accomplished by placing one figure on top of the other or by comparing the measurements of all sides and angles.
A quadrilateral is a closed planar (two-dimensional) figure with four sides that are line segments.
A parallelogram is a quadrilateral whose opposite sides are parallel and opposite angles are congruent.
A rectangle is a parallelogram with four right angles.
Rectangles have special characteristics (such as diagonals are bisectors) that are true for any rectangle.
To bisect means to divide into two equal parts.
A square is a rectangle with four congruent sides or a rhombus with four right angles.
A rhombus is a parallelogram with four congruent sides.
A trapezoid is a quadrilateral with exactly one pair of parallel sides.
The parallel sides of a trapezoid are called bases, and the nonparallel sides are called legs.
An iscoles trapezoid is If the legs have the same length, then the trapezoid.
A kite is a quadrilateral with two pairs of adjacent congruent sides. One pair of opposite angles is congruent.
Quadrilaterals can be sorted according to common attributes, using a variety of materials.
a parallelogram, rectangle, rhombus, and square each have two pairs of parallel sides;
a trapezoid has only one pair of parallel sides; other quadrilaterals have two pairs of parallel sides.
a rectangle has four 90° angles;
a trapezoid may have zero or two 90° angles.
A square is a special type of both a rectangle and a rhombus,
The sum of the measures of the angles of a quadrilateral is 360°.
A kite has two pairs of congruent, adjacent sides. The two pairs are not congruent to each other.
what is a polygon a plane figure with at least three straight sides and angles, and typically five or more
