Questions

1. What is a flat shape with four equal sides and four right angles called?

   1. Rectangle
   2. Rhombus
   3. Square
   4. Trapezoid
   Show answer

   Answer: Square

   A square has 4 equal sides AND 4 right angles, which distinguishes it from a rhombus (equal sides, no right angles).

2. A ray has two endpoints.

   Show answer

   Answer: False

   A ray has exactly ONE endpoint. It starts at that point and extends forever in one direction.

3. A triangle with all three sides of equal length is called an ___ triangle.

   Show answer

   Answer: equilateral

   Equilateral means 'equal sides.' All three sides of an equilateral triangle are the same length.

4. Which pair of lines never intersect?

   1. Perpendicular
   2. Parallel
   3. Intersecting
   4. Crossing
   Show answer

   Answer: Parallel

   Parallel lines are always the same distance apart and never cross, no matter how far they extend.

5. How many sides does a hexagon have?

   1. 5
   2. 6
   3. 7
   4. 8
   Show answer

   Answer: 6

   A hexagon has 6 sides. The prefix hexa- means six.

6. A rectangle is always a parallelogram.

   Show answer

   Answer: True

   A rectangle has 2 pairs of parallel sides and opposite sides of equal length, making it a parallelogram.

7. An angle less than 90 degrees is called an ___ angle.

   Show answer

   Answer: acute

   Acute angles measure less than 90 degrees. Right angles are exactly 90°; obtuse angles are greater than 90°.

8. Which shape has exactly one pair of parallel sides?

   1. Square
   2. Parallelogram
   3. Trapezoid
   4. Rectangle
   Show answer

   Answer: Trapezoid

   A trapezoid has exactly one pair of parallel sides. Squares, rectangles, and parallelograms all have two pairs.

9. A right triangle can also be an equilateral triangle.

   Show answer

   Answer: False

   An equilateral triangle has all angles equal to 60°. A right triangle must have one 90° angle. They cannot coexist.

10. A line that goes on forever in both directions has ___ endpoints.

    Show answer

    Answer: no

    A line extends infinitely in both directions; it has no starting or ending point.
