Perimeter and Angles Review

Calculate the perimeter of a square with side length 5 units.

• The perimeter of the square is 10 units.

• The perimeter of the square is 15 units.

• The perimeter of the square is 25 units.

• The perimeter of the square is 20 units.

Identify the type of angle formed when two lines meet at a right angle.

• Right angle

• Acute angle

• Obtuse angle

• Straight angle

Explain the concept of perimeter using a simple example.

• Perimeter is only applicable to circles and not other shapes

• The perimeter of a square is the area inside the square

• The perimeter of a square is calculated by multiplying the length of one side by 4

• For example, the perimeter of a square with sides of length 4 units would be 4 + 4 + 4 + 4 = 16 units.

How many right angles does a rectangle have?

• 2

• 3

• 5

• 4

Identify the type of angle formed when two lines meet at an angle less than 90 degrees.

• Obtuse angle

• Right angle

• Acute angle

• Straight angle

What is the difference between a regular polygon and an irregular polygon?

• The difference between a regular polygon and an irregular polygon is that a regular polygon has all sides and angles equal, while an irregular polygon has sides and angles of different lengths and measures.

• A regular polygon has all sides and angles equal but irregular polygon has only sides equal

• A regular polygon has all angles equal but irregular polygon has all sides equal

• A regular polygon has all sides equal but irregular polygon has all angles equal

Calculate the perimeter of a rectangle with length 8 units and width 4 units.

• Perimeter = 2 x (8 + 4) = 2 x 12 = 24 units

• Perimeter = 8 + 4 = 12 units

• Perimeter = 2 x (8 x 4) = 2 x 32 = 64 units

• Perimeter = 2 x (8 - 4) = 2 x 4 = 8 units

How many acute angles does a triangle have?

• 3

• 0

• 4

• 2
