Quick Solutions Inside!
To assist with your understanding of Geometry Worksheet 1.1, we’ll provide some quick solutions to typical questions you might encounter. For ease of reading, we will categorize the solutions by topic.
Basic Shapes and Properties
Question 1: Identify the shape
Identify the following shapes based on their properties:
Shape | Properties |
---|---|
Triangle | 3 sides, sum of interior angles = 180° |
Square | 4 equal sides, 90° angles |
Circle | No sides, infinite line of symmetry |
Solution:
- Triangle: Recognizable by its three sides and angle sum.
- Square: Defined by four equal sides and right angles.
- Circle: Characterized by its round shape and no sides.
Angle Properties
Question 2: Classifying Angles
Classify the following angles:
- 30°
- 90°
- 120°
Angle Measurement | Classification |
---|---|
30° | Acute |
90° | Right |
120° | Obtuse |
Solution:
- 30°: Acute angle (less than 90°).
- 90°: Right angle (exactly 90°).
- 120°: Obtuse angle (greater than 90° but less than 180°).
Perimeter and Area Calculations
Question 3: Calculate the Area and Perimeter
For a rectangle with length 5 cm and width 3 cm, calculate the area and perimeter.
- Area = length × width
- Perimeter = 2(length + width)
Calculation | Result |
---|---|
Area | 15 cm² |
Perimeter | 16 cm |
Solution:
- Area: ( 5 , \text{cm} \times 3 , \text{cm} = 15 , \text{cm}² )
- Perimeter: ( 2(5 , \text{cm} + 3 , \text{cm}) = 16 , \text{cm} )
Pythagorean Theorem
Question 4: Find the Hypotenuse
In a right triangle, if one side is 6 cm and the other side is 8 cm, what is the length of the hypotenuse?
Using the Pythagorean theorem:
- ( c = \sqrt{a² + b²} )
Side Lengths | Calculation | Result |
---|---|---|
6 cm & 8 cm | ( c = \sqrt{6² + 8²} ) | 10 cm |
Solution:
- Length of the hypotenuse ( c ): [ c = \sqrt{6² + 8²} = \sqrt{36 + 64} = \sqrt{100} = 10 , \text{cm} ]
