MAAP Geometry 1 — Questions and Answers
Question 1: What is the sum of the interior angles of a triangle?
- 180° (Correct answer)
- 360°
- 90°
- 270°
Correct answer: 180°
The sum of the three interior angles in any triangle is always 180°.
Question 2: What is the circumference of a circle with radius 7? (Use π ≈ 3.14)
- 43.96 (Correct answer)
- 21.98
- 153.86
- 87.92
Correct answer: 43.96
Circumference = 2πr = 2 × 3.14 × 7 = 43.96.
Question 3: Two lines that intersect at 90° are called:
- Perpendicular lines (Correct answer)
- Parallel lines
- Skew lines
- Congruent lines
Correct answer: Perpendicular lines
Lines that meet at a right angle (90°) are perpendicular to each other.
Question 4: What type of triangle has all three sides of different lengths?
- Scalene (Correct answer)
- Equilateral
- Isosceles
- Right
Correct answer: Scalene
A scalene triangle has three sides of different lengths and three different angles.
Question 5: What is the area of a triangle with base 10 and height 6?
- 30 (Correct answer)
- 60
- 16
- 120
Correct answer: 30
Area of a triangle = (1/2) × base × height = (1/2) × 10 × 6 = 30.
Question 6: An angle that measures exactly 90° is called a:
- Right angle (Correct answer)
- Acute angle
- Obtuse angle
- Straight angle
Correct answer: Right angle
An angle measuring exactly 90° is defined as a right angle.
