Maths Flashcards
What is the formula for pythag
A squared +B squared = C squared
What do you need to write down for Reflecting
Reflection
Equation of the mirror line
What do you need to write down for Translating
Translation
(x)
(y)
What do you need to write down for Enlarging
Enlargement
Scale factor
Center of Enlargement
What do you need to write down for Rotation
Rotation
Angle+Direction
Center of rotation
How do you do reflection
Copy shape + part of mirror line on tracing paper, flip tracing paper and match up mirror line, Draw shape
How do you do translations
Choose a corner + move it
X = across
Positive = right
Negative = left
Y = height
Positive = up
Negative = down
How do you do enlargements
Find the center of enlargement, count how far up and across it is to a corner, multiply the distance by the scale factor, this takes us to the corner of the new shape, draw shape SF times as big from that corner
How do you do Rotation
Copy shape and point onto tracing paper, draw a line from the point to the closest corner of the shape, put pencil on the rotation point and turn it the required amount, draw shape
