Answer Key
Multiple Choice Questions:
- b) 180 degrees
- c) 8π cm (Circumference = 2πr)
- b) Opposite sides are equal and parallel
- d) It quadruples (Area = side²)
Short Answer Questions:
-
A right angle is an angle that measures 90 degrees. Examples include the corners of a square or rectangle.
-
The area of a triangle is given by the formula \( A = \frac{1}{2} \times \text{base} \times \text{height} \), where the base is the length of the base of the triangle and the height is the perpendicular distance from the base to the opposite vertex.
Problem Solving:
-
Area of a trapezoid = \( \frac{1}{2} \times (b_1 + b_2) \times h = \frac{1}{2} \times (10 + 6) \times 4 = 32 , \text{cm}^2 \).
-
Volume of a cylinder = \( V = \pi r^2 h = \pi (3^2)(5) = 45\pi \approx 141.3 , \text{cm}^3 \) (using 3.14 for π).
-
Perimeter of a pentagon = \( 5 \times \text{side length} = 5 \times 6 = 30 , \text{cm} \).
Bonus Question:
- A rhombus is a quadrilateral with all four sides of equal length, while a rectangle has opposite sides that are equal and all angles measuring 90 degrees. Additionally, the diagonals of a rhombus intersect at angles but are not necessarily equal.
