Study Notes

Measurement Tools

Metric ruler: Measures lengths in millimeters, centimeters, and meters.
Metric scale: A straight edge for architectural drawings, divided into centimeters and further into millimeters.
Standard ruler: Measures lengths in English units like inches, feet, and yards.

Number Types

Mixed number: Combination of a whole number with a fraction or decimal (e.g., 5.75, 1 1/4).
Negative numbers: Values less than zero, such as -1, -2, -3.
Positive numbers: Values greater than zero, including 1, 2, 3, etc.
Whole numbers: Non-negative integers excluding fractions and decimals.

Fractions and Angles

Numerator: The top part of a fraction, indicating portions (e.g., in 1/2, the numerator is 1).
Obtuse angle: Measures between 90 and 180 degrees.
Right angle: Measures exactly 90 degrees, formed by perpendicular lines.
Opposite angles: Formed by intersecting straight lines, always equal.

Shapes and Geometry

Perimeter: The total distance around a closed shape like a rectangle, square, or circle.
Pi (π): Approximately 3.14, used to calculate areas and circumferences of circles.
Radius: Distance from a circle's center to any point on its circumference, half of the diameter.
Rectangle: A four-sided shape with four right angles; opposite sides are equal and parallel.
Square: A special rectangle with four equal sides and four right angles.
Triangle: A closed figure with three sides and three angles.
Right triangle: Contains one right angle (90 degrees).
Scalene triangle: All sides have different lengths.

Arithmetic Concepts

Product: Result of multiplication (e.g., product of 6 x 6 is 36).
Quotient: Result of division (e.g., dividing 6 by 2 gives 3).
Sum: Total from addition (e.g., 7 + 8 equals 15).
Remainder: The leftover value in a division operation.

Other Geometric Terms

Vertex: The point where two or more lines or curves meet.
Volume: Measurement of three-dimensional space expressed in cubic units.
Straight angle: Measures exactly 180 degrees and represents a flat line.
