GCSE Secondary Maths Age 13-17 - Geometry & Measures: Translation - Explained

The video tutorial covers a GCSE exam question from summer 2017, focusing on describing a single transformation that maps shape A onto shape B. The teacher explains the four types of transformations: translation, rotation, reflection, and enlargement, emphasizing that the task requires identifying a single transformation. The tutorial details how to describe a translation using vector form, moving horizontally and vertically on a grid. The teacher highlights the importance of stating the transformation type and vector to score marks, stressing that only one transformation should be used.

What is the main task described in the GCSE exam question?

• To describe a single transformation that maps shape A onto shape B

• To calculate the area of shape A

• To compare the sizes of shapes A and B

• To identify multiple transformations for shape A

Which of the following is NOT one of the four transformations mentioned?

• Rotation

• Translation

• Reflection

• Distortion

How is a translation described in the context of the exam question?

• Through a narrative description

• In vector form

• By using a color code

• By drawing a diagram

What is the vector form used to describe the translation in the question?

• [-3, 4]

• [4, 3]

• [4, -3]

• [3, -4]

Why is it important to identify the transformation as a single one?

• Because it saves time during the exam

• Because multiple transformations are more complex

• Because the question specifically asks for a single transformation

• Because single transformations are easier to score
