How do you describe transformations GCSE?
A transformation is a way of changing the size or position of a shape. Every point in the image is the same distance from the mirror line as the original shape. The line joining a point on the original shape to the same point on the image is perpendicular to the mirror line.
How would you describe a single transformation enlargement?
Enlargement is an example of a transformation. A transformation is a way of changing the size or position of a shape. To enlarge a shape, a centre of enlargement is required. When a shape is enlarged from a centre of enlargement, the distances from the centre to each point are multiplied by the scale factor.
How would you describe a single transformation reflection?
A reflection is a type of transformation. It ‘maps’ one shape onto another. When a shape is reflected a mirror image is created. If the shape and size remain unchanged, the two images are congruent.
How do you write a transformation?
The function translation / transformation rules:
- f (x) + b shifts the function b units upward.
- f (x) − b shifts the function b units downward.
- f (x + b) shifts the function b units to the left.
- f (x − b) shifts the function b units to the right.
- −f (x) reflects the function in the x-axis (that is, upside-down).
How do you enlarge by a scale factor of 2?
To enlarge a shape, multiply all lengths of the shape by the scale factor. The scale factor tells us how many times larger the shape will be. For example, enlarging a shape by scale factor 2 means that all of the sides will become 2 times longer. This rectangle is 1 square wide and 2 squares long.
What is single transformation in maths?
Sometimes a shape is transformed using more than one step, for example a reflection followed by a rotation. The combination of transformations can usually be described as a single transformation.
What is transformation rules?
Definition of transformation rule : a principle in logic establishing the conditions under which one statement can be derived or validly deduced from one or more other statements especially in a formalized language. — called also rule of deduction.
What is a transformation in math example?
Translation happens when we move the image without changing anything in it. Hence the shape, size, and orientation remain the same. For example: The given shape in blue is shifted 5 units down as shown by the red arrow, and the transformed image formed is shown in maroon.
What is a transformation in GCSE Maths?
Raise maths attainment across your school with hundreds of flexible and easy to use GCSE maths worksheets and lessons designed by teachers for teachers. A transformation is something which changes the position or size of an object. There are four types of transformation, reflection, rotation, translation and enlargement.
What are the 4 types of transformations?
There are 4 types of transformation: translation, rotation, reflection, and enlargement . You need to be able to perform each transformation as well as identify which transformations have been performed.
What is a transformation?
A transformation is something which changes the position or size of an object. There are four types of transformation, reflection, rotation, translation and enlargement. Reflections use a mirror line and result in the shape being flipped.
How do you translate and rotate a shape?
If you shift each corner 4 spaces left and 1 space up, all that remains is to join up your new set of corners, and you get the translated shape. The resulting shape is shown on the left. The next type of transformation is rotation. To rotate a shape or describe a rotation you need these three details:
