Geometry Tips

Answer submission

  • Use the correct notation! Answers with incorrect notations will result in an answer being marked as incorrect. Some common notations include:
    • Line segment: Two points with a line over it refers to a line segment. If it does not have a line over two points (e.g. AB), it denotes the length of that line segment
    • ∠ABC: Name of angle ABC
    • m∠ABC: Measure of angle ABC (e.g. 45°)
    • Congruent (≅) indicates identical in shape and size. You can say two line segments are congruent ( ≅ ) or two angles are congruent (∠ABC ≅ ∠XYZ)
    • Equal (=) indicates same distance or measure. You can say the lengths of two lines segments are equal (AB = CD) or two measures of angles are equal m∠ABC = m∠XYZ
  • Uppercase letters ≠ lowercase letters (e.g. Points should be written in uppercase)
  • Read each question carefully to understand how the answer should be written or selected on the diagram/drop-down menu

Line segments

  • To indicate a line segment, students must place a line above the written endpoints (e.g. not AB)
  • First, select the line segment from the math palette and then enter the points

Incorrect

 

Correct

Points

In Geometry there is a difference between uppercase and lowercase letters – points should be written in uppercase

Correct

 

Read questions carefully

Read the question carefully to determine how your answer should be submitted

Select on the diagram

 

  • In the example above, there’s no answer box because the student needs to select the appropriate portions of the diagram by clicking on them

 

  • In the example above, there’s no answer box because the student needs to select the appropriate angle by clicking on it

Working with π

  • Some questions ask the student to use 3.14 to approximate π

 

  • Other questions require students to submit π in their answers
  • For answers that require pi, select it from the math palette

Multi-part answers

Some questions require students to submit multiple answers per question

Multi-part answers

  • In this example, the student needs to 1) select the set of parallel lines by clicking on the appropriate lines and 2) choose the correct answer from the drop-down menu

Proofs

  • Students must fill in all the blanks correctly and choose the correct reasons from the dropdown menu to get the answer correct
