Read the first 6 Geometry and Measurement flashcards as text

  1. A trapezoid has bases of 8 and 12 and a height of 5. What is its area?

    Answer: 50

    Area = ½ × (b₁ + b₂) × h = ½ × (8 + 12) × 5 = ½ × 100 = 50.

  2. What type of triangle has all three sides of equal length?

    Answer: Equilateral

    An equilateral triangle has all three sides equal and all angles measuring 60°.

  3. What is the area of a circle with diameter 10? (Use π ≈ 3.14)

    Answer: 78.5

    Radius = 5, Area = πr² = 3.14 × 25 = 78.5.

  4. Two parallel lines are cut by a transversal. Which angle pair is always equal?

    Answer: Alternate interior angles

    Alternate interior angles are congruent when formed by parallel lines and a transversal.

  5. What is the perimeter of a regular hexagon with side length 6 cm?

    Answer: 36 cm

    A regular hexagon has 6 equal sides, so perimeter = 6 × 6 = 36 cm.

  6. A cylinder has radius 3 and height 7. What is its volume? (Use π ≈ 3.14)

    Answer: 197.82

    Volume = πr²h = 3.14 × 9 × 7 = 197.82.
