Study Notes
Number Names
- Number names convert numerical values into their equivalent word forms (e.g., 1 is "one," 2 is "two").
- They are used for clarity in communication, especially in writing checks or official documents.
Types of Angles
- Acute Angle: Measures less than 90 degrees.
- Right Angle: Measures exactly 90 degrees; often marked by a small square in illustrations.
- Obtuse Angle: Measures more than 90 degrees but less than 180 degrees.
- Straight Angle: Measures exactly 180 degrees, forming a straight line.
- Reflex Angle: Measures more than 180 degrees but less than 360 degrees.
Drawing an Angle
- To draw an angle, use a protractor for accuracy, ensuring the vertex is at the center.
- Define the angle's measurement and create rays extending from the vertex, forming the angle.
Word Problem
- Word problems require translating a scenario into a mathematical equation to solve for an unknown.
- Key elements include identifying what is given, the question being asked, and relevant operations to apply.
Number of Sides and Angles
- The number of sides in a polygon corresponds directly to the number of angles.
- For instance, a triangle has 3 sides and 3 angles, while a square has 4 sides and 4 angles.
Convert to Improper Fraction
- An improper fraction has a numerator larger than the denominator (e.g., 9/4).
- To convert a mixed number to an improper fraction, multiply the whole number by the denominator and add the numerator.
Finding Multiples
- A multiple of a number is obtained by multiplying that number by an integer (e.g., multiples of 3 are 3, 6, 9, etc.).
- To find multiples, choose a number and iterate through integers to generate the sequence.
