MICRO LESSON 1
Basic Angle Types
Picture it:
A clock makes different angles as hands move.
Simple:
Angles may be acute, right, obtuse, straight or reflex.
Example:
90° is a right angle.
Quick Check:
What type is 120°?
MICRO LESSON 2
Adjacent Angles
Picture it:
Two neighbouring rooms share a wall.
Simple:
Adjacent angles share a vertex and one arm.
Example:
∠AOB and ∠BOC.
Quick Check:
What do adjacent angles share?
MICRO LESSON 3
Linear Pair
Picture it:
Two angles on a straight line add to 180°.
Simple:
A linear pair consists of adjacent supplementary angles.
Example:
110° and 70° form a linear pair.
Quick Check:
If one is 65°, find the other.
MICRO LESSON 4
Vertically Opposite Angles
Picture it:
Two roads crossing form opposite angle pairs.
Simple:
Vertically opposite angles are equal.
Example:
If one is 50°, the opposite is 50°.
Quick Check:
Are vertically opposite angles adjacent?
MICRO LESSON 5
Parallel Lines and Transversal
Picture it:
A road crossing two parallel railway tracks creates angle patterns.
Simple:
A transversal intersects two or more lines.
Example:
Corresponding and alternate angles appear.
Quick Check:
What is a transversal?
MICRO LESSON 6
Corresponding Angles
Picture it:
Matching corners have equal angles when lines are parallel.
Simple:
Corresponding angles are equal.
Example:
Top-right at each intersection matches.
Quick Check:
What condition makes them equal?
MICRO LESSON 7
Alternate Interior Angles
Picture it:
Angles inside parallel lines on opposite sides of transversal are equal.
Simple:
These are alternate interior angles.
Example:
Z-shape helps identify them.
Quick Check:
Name the visual memory shape.
MICRO LESSON 8
Co-interior Angles
Picture it:
Same-side interior angles add to 180°.
Simple:
They are supplementary for parallel lines.
Example:
110° and 70°.
Quick Check:
If one is 120°, find the other.
