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

The video tutorial covers a transformation question involving reflection and translation on a grid. It begins with reflecting shape A in the line y = X, explaining the steps and marks for correct reflection. The tutorial then describes the single transformation from B to C, identifying it as a translation. It emphasizes the importance of expressing translation in vector form and concludes with tips on handling transformation questions.

What is the first step in reflecting a shape across the line y = X on a grid?

• Rotate the shape 90 degrees.

• Identify the distance of each vertex from the line y = X.

• Translate the shape horizontally.

• Use tracing paper to trace the shape.

Which of the following is NOT a type of transformation?

• Distortion

• Rotation

• Translation

• Reflection

What is the correct term for moving a shape without rotating or resizing it?

• Enlargement

• Rotation

• Translation

• Reflection

How should a translation be expressed to ensure clarity?

• As a coordinate pair

• In vector form

• As a reflection

• Using descriptive words like 'across' and 'down'

If a shape moves 4 units right and 1 unit down, how is this translation represented in vector form?

• [4, -1]

• (4, 1)

• 4, -1

• (4, -1)
