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 (Ï€): 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.
