What is the sum of interior angles of any triangle?
Answer: 180°
The three interior angles of any triangle always add up to exactly 180°.
A point, a line segment, and a ray all differ. Which one extends infinitely in both directions?
Answer: A line
A line extends infinitely in both directions, while a ray extends in only one direction and a segment has two endpoints.
What is the area of a circle with a diameter of 6 cm? (Use π ≈ 3.14)
Answer: 28.26 cm²
Radius = 3 cm; Area = πr² = 3.14 × 3² = 3.14 × 9 = 28.26 cm².
Two angles are complementary. One measures 32°. What is the other?
Answer: 58°
Complementary angles sum to 90°, so 90° − 32° = 58°.
A cube has a side length of 5 cm. What is its volume?
Answer: 125 cm³
Volume of a cube = side³ = 5³ = 125 cm³.
Which term describes the distance around the outside of any polygon?
Answer: Perimeter
Perimeter is the total length of all sides around a polygon.
An equilateral triangle has one angle that measures 70°. What are the other two angles?
Answer: This is impossible; all angles in an equilateral triangle are 60°
An equilateral triangle has three equal angles of 60° each, so no angle can be 70°.
