Tom has a white rectangular card which is orange on the other side. He folds the card along its diagonal AB. Find ∠z.
Why Students Find Folded Diagonal Questions Challenging
Many Primary 6 students struggle with this type of question. It requires strong visualisation skills and the ability to think about a flat card in three dimensions. Understanding how folding affects angles is the key to solving the problem confidently.
Step-by-Step Strategy for Solving
- Identify all of the unknown angles: Start by seeing which angle is easiest to solve first.
- Label the right angles clearly: Check if any angles are halved due to the fold.
- Apply the sum of angles in a triangle
- Work systematically: Tackle one angle at a time to build confidence.
For self motivated learners aiming to become confident in geometry, mastering these strategies builds not only problem-solving skills but also the ability to handle other tricky Primary mathematics questions independently. Students who practice this approach find that even the most intimidating folded rectangular card or folded diagonally questions become manageable.

- hello
- Hi, i dont understand
- y = 16 i understand
- ok wait ah i draw for you
- so like you found x is 74, and y is 16 right
- cos the paper is folded, so originally, the corner with y is 90
- 90 - 16 = 74. half of it (cos it's folded), is 74 / 2 = 37
- then you can find z. z = 180 - 90 - 37 = 53
- ahh i got it thanks
- np!
- itll help if you can give me a 5-star rating : )Thank you
