Whether you're struggling with formulas or need help solving numerical problems step-by-step, this video will guide you with clear explanations and solved examples.
✅ What You’ll Learn in This Video:
Introduction to Transformation Matrix :
What is a Transformation Matrix? (Definition and Importance)
Purpose: To represent geometric transformations using matrix multiplication.
General Formula:
$$
\begin{bmatrix}
x' \
y'
\end{bmatrix}
T
\cdot
\begin{bmatrix}
x \
y
\end{bmatrix}
$
Where T isthetransformationmatrix,and (x, y) $ are the original coordinates.
Key Concepts :
Reflection Matrices :
Reflection on the X-Axis:
T=[
1
0
0
−1
]
Reflection on the Y-Axis:
T=[
−1
0
0
1
]
Reflection on X=Y:
T=[
0
1
1
0
]
Rotation Matrices :
Rotation by θ degrees about the origin:
T=[
cosθ
sinθ
−sinθ
cosθ
]
Example: For 90
∘
counterclockwise rotation:
T=[
0
1
−1
0
]
Translation Matrices :
Translation cannot be represented by a 2x2 matrix but can be done using homogeneous coordinates.
Enlargement Matrices :
Enlargement with scale factor k:
T=[
k
0
0
k
]
Combined Transformations :
Multiply transformation matrices in the correct order to combine multiple transformations.
Example: Reflection on Y-Axis followed by Reflection on X=Y:
T
combined
=T
X=Y
⋅T
Y-Axis
