PAPA PAPA Geometry & Measurement 2 — Questions and Answers
Question 1: Using the Pythagorean theorem, find the hypotenuse of a right triangle with legs of 3 and 4.
- 5 (Correct answer)
- 6
- 7
- 8
Correct answer: 5
a² + b² = c²: 9 + 16 = 25, so c = √25 = 5.
Question 2: What is the circumference of a circle with radius 7? (Use π ≈ 3.14)
- 21.98
- 43.96 (Correct answer)
- 153.86
- 14
Correct answer: 43.96
Circumference = 2πr = 2 × 3.14 × 7 = 43.96.
Question 3: Two angles that together form a straight line (180°) are called:
- Complementary angles
- Vertical angles
- Supplementary angles (Correct answer)
- Congruent angles
Correct answer: Supplementary angles
Supplementary angles are two angles whose measures add up to 180°.
Question 4: A triangle with all three sides of equal length is called:
- Isosceles
- Scalene
- Right
- Equilateral (Correct answer)
Correct answer: Equilateral
An equilateral triangle has all three sides and all three angles equal (each 60°).
Question 5: What is the area of a triangle with base 10 cm and height 6 cm?
- 60 cm²
- 30 cm² (Correct answer)
- 16 cm²
- 40 cm²
Correct answer: 30 cm²
Area of a triangle = ½ × base × height = ½ × 10 × 6 = 30 cm².
Question 6: How many degrees are in a full rotation (complete circle)?
- 180°
- 270°
- 360° (Correct answer)
- 90°
Correct answer: 360°
A full rotation around a central point equals 360 degrees.
