Which type of triangle has all three sides of equal length?
Answer: Equilateral
An equilateral triangle has all three sides equal in length and all angles equal to 60°.
What is the surface area of a cube with side length 4 cm?
Answer: 96 cm²
Surface area = 6 × side² = 6 × 16 = 96 cm².
What is the midpoint of the line segment from (0, 0) to (8, 6)?
Answer: (4, 3)
Midpoint = ((0+8)/2, (0+6)/2) = (4, 3).
An angle that measures exactly 90° is called a:
Answer: Right angle
A right angle measures exactly 90° and is commonly shown with a small square symbol.
What is the volume of a cylinder with radius 3 and height 10? (Use π ≈ 3.14)
Answer: 282.6 cubic units
Volume = πr²h = 3.14 × 9 × 10 = 282.6 cubic units.
If two angles in a triangle measure 45° and 75°, what is the third angle?
Answer: 60°
The angles in a triangle sum to 180°; third angle = 180 − 45 − 75 = 60°.
