Classify angles of two-dimensional shapes using benchmark angles (45°, 90°, 180°, and 360°)

Remarks

Use pictures of real world objects or diagrams of shapes with angles and ask students to classify the given angles by using benchmark angles.

 

Use protractor to draw the angles of 45, 90, 180, and 360 degrees.

Test Item Specifications
  • Item Type(s): This benchmark may be assessed using: MC item(s)

  • Clarification :
    Students will classify angles by the following terms: acute, obtuse, right, or straight.

    Students will identify the benchmark angle measurements of 45°, 90°, 180°, and/or 360°.
  • Content Limits :
    Items may include the following vocabulary terms: ray, angle, (acute, obtuse, right, straight), and perpendicular lines.

    Items will not include the vocabulary terms: complementary, supplementary, and vertical.

    Items will not require the use of a protractor or measuring an angle to the nearest degree.

    Items may include the geometric notation for angle (∠) and degrees (°).
  • Stimulus Attributes :
    Items will include only two-dimensional figures.

    Items may be set in either a real-world or a mathematical context.

    Graphics should be used in most of these items, as appropriate.
