Key Topics to Revise
1
Shapes: Open and Closed
- A closed shape is one where all sides are connected and there are no openings.
- An open shape is one where the sides are not fully connected – it has at least one opening.
- When we make a shape with matchsticks, we can form many different closed shapes using the same number of matchsticks.
2
Angles: What Are They?
- An angle is formed when two straight lines meet at a point (corner).
- The amount of opening between two lines is the angle – bigger opening means bigger angle.
- When we change the angle between two matchsticks (or sides), the whole shape changes.
3
Types of Angles: Right Angle, Less Than Right Angle, More Than Right Angle
- A RIGHT ANGLE looks like the corner of a square, the letter L, or the corner of a book. It measures exactly 90°.
- We use the symbol ∟ or a small square at the corner to show a right angle.
- An angle LESS THAN a right angle is a smaller, sharper, more pointed angle. It measures less than 90°. This is also called an ACUTE angle.
4
Measuring Angles: The Degree Clock and Protractor
- Angles are measured in DEGREES. The symbol for degree is °.
- A right angle = 90°
- Half of a right angle = 45°
