Measurement and Geometry Flashcards

What is the area of a parallelogram with a base of 9 m and a height of 5 m?

Answer: 45 m²

Area of a parallelogram = base × height = 9 × 5 = 45 m².

Point P is located at (−3, 4) on a coordinate plane. In which quadrant is this point?

Answer: Quadrant II

Quadrant II contains points with negative x-values and positive y-values, like (−3, 4).

How many lines of symmetry does a regular hexagon have?

Answer: 6

A regular hexagon has 6 lines of symmetry — three through opposite vertices and three through midpoints of opposite sides.

A cylinder has a radius of 3 cm and a height of 10 cm. What is its volume? (Use π ≈ 3.14)

Answer: 282.6 cm³

Volume of a cylinder = π × r² × h = 3.14 × 9 × 10 = 282.6 cm³.

A farmer has a triangular plot of land with a base of 120 feet and a height of 80 feet. What is the area?

Answer: 4,800 ft²

Area = ½ × base × height = ½ × 120 × 80 = 4,800 ft².

Which transformation moves every point of a figure the same distance in the same direction without changing its size or shape?

Answer: Translation

A translation slides a figure without flipping, turning, or resizing it — every point moves the same distance and direction.

The temperature dropped from 72°F to 58°F. By how many degrees Celsius did it drop? (Use: °C = (°F − 32) × 5/9)

Answer: 7.78°C

A 14°F drop × 5/9 = 7.78°C, since only the difference matters and the 32-offset cancels out.
