Practical geometry class 8 important formulas:
Perimeter of a polygon: The perimeter of a polygon is the sum of the lengths of all its sides. For a polygon with n sides, the perimeter can be calculated as P = a1 + a2 + ... + an, where ai is the length of the ith side.
Area of a triangle: The area of a triangle can be calculated using the formula A = 1/2 × b × h, where b is the base of the triangle, and h is its height.
Area of a rectangle: The area of a rectangle can be calculated using the formula A = l × w, where l is the length of the rectangle and w is its width.
Area of a square: The area of a square can be calculated using the formula A = s², where s is the length of one side of the square.
Circumference of a circle: The circumference of a circle can be calculated using the formula C = 2πr, where r is the radius of the circle, and π is a constant equal to approximately 3.14.
Area of a circle: The area of a circle can be calculated using the formula A = πr², where r is the radius of the circle.
Pythagorean theorem: The Pythagorean theorem states that in a right-angled triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. Mathematically, it can be expressed as a² + b² = c², where a and b are the lengths of the other two sides, and c is the length of the hypotenuse.
Similarity of triangles: Two triangles are said to be similar if their corresponding angles are equal, and their corresponding sides are in proportion. This can be expressed as a ratio of the lengths of the corresponding sides, known as the scale factor.
Practical geometry class 8 Extra Questions and Answers:
Exercise 1: Find the perimeter and area of a rectangle with length 8 cm and width 5 cm.
Perimeter = 2(l + w) = 2(8 + 5) = 26 cm
Area = lw = 8 x 5 = 40 cm²
Exercise 2: Find the length of the hypotenuse of a right-angled triangle with base 6 cm and height 8 cm.
Using the Pythagorean theorem, a² + b² = c², where a and b are the lengths of the other two sides, and c is the length of the hypotenuse.
a = 6 cm
b = 8 cm
c² = a² + b² = 6² + 8² = 100
c = √100 = 10 cm
Exercise 3: Find the perimeter and area of a square with side length 12 cm.
Perimeter = 4s = 4 x 12 = 48 cm
Area = s² = 12² = 144 cm²
Exercise 4: Find the circumference and area of a circle with a radius 5 cm.
Circumference = 2πr = 2 x π x 5 = 31.4 cm (approx.)
Area = πr² = π x 5² = 78.5 cm² (approx.)
Exercise 5: Find the length of the missing side of a similar triangle with a scale factor of 2, given that one side of the smaller triangle is 4 cm and the corresponding side of the larger triangle is 8 cm.
The sides of similar triangles are proportional to the scale factor. Therefore, the missing side is 2 x 4 = 8 cm.
