1.
A ___________________ has exactly one pair of parallel sides.
Explanation
A trapezoid is a quadrilateral that has exactly one pair of parallel sides. The other two sides are non-parallel and can be of different lengths. Therefore, a trapezoid fits the description of having exactly one pair of parallel sides.
2.
A ______________ has four congruent sides and opposite sides are parallel.
Explanation
A quadrilateral is a polygon with four sides. When all four sides are congruent (equal in length) and opposite sides are parallel, it is classified as a rhombus. This geometric property distinguishes a rhombus from other quadrilaterals, making it a special type of parallelogram.
3.
A ___________________ has four right angles, opposite sides are parallel, and opposite sides are congruent.
Explanation
A rectangle is a quadrilateral that satisfies all the given conditions. It has four right angles, meaning each of its interior angles measures 90 degrees. The opposite sides of a rectangle are parallel, which means they never intersect. Additionally, the opposite sides of a rectangle are congruent, meaning they have the same length. Therefore, a rectangle is the correct answer to this question.
4.
A ________________ has four right angles and all sides are congruent.
Explanation
A square is a shape that has four right angles and all sides are congruent. This means that each angle in a square measures 90 degrees, and all four sides of a square have the same length. Therefore, a square fits the description given in the question.
5.
A square is a rhombus.
Correct Answer
A. True
Explanation
A square is a rhombus because both shapes have four equal sides. While a square has four right angles, a rhombus has four equal angles that are not necessarily right angles. Therefore, all squares can be considered rhombuses, but not all rhombuses are squares.
6.
A trapezoid is a parallelogram.
Correct Answer
B. False
Explanation
A trapezoid is not a parallelogram because a parallelogram has two pairs of parallel sides, while a trapezoid has only one pair of parallel sides. In a trapezoid, the other two sides are not parallel to each other. Therefore, the statement that a trapezoid is a parallelogram is false.
7.
A rectangle is a square.
Correct Answer
B. False
Explanation
A rectangle is not a square because although both shapes have four sides, a square has all sides of equal length, while a rectangle has opposite sides of equal length. Therefore, a square is a specific type of rectangle, but not all rectangles are squares.
8.
A square can be a rhombus and a rectangle.
Correct Answer
A. True
Explanation
A square can be a rhombus because a rhombus is a quadrilateral with all sides of equal length. Since a square is a quadrilateral with all sides of equal length, it meets the criteria to be a rhombus. Additionally, a square can be a rectangle because a rectangle is a quadrilateral with all angles equal to 90 degrees. Since a square has all angles equal to 90 degrees, it also meets the criteria to be a rectangle. Therefore, the statement is true.
9.
What is the polygon above?
Correct Answer
C. Hexagon
Explanation
The polygon above is a hexagon because it has six sides. A hexagon is a polygon with six straight sides and six angles.
10.
What is the above polygon?
Correct Answer
A. Decagon
Explanation
The above polygon is a decagon because it has ten sides. A decagon is a polygon with ten straight sides and ten angles.
11.
What is the above polygon?
Correct Answer
C. Pentagon
Explanation
The above polygon is a pentagon because it has five sides. A hexagon has six sides, and a quadrilateral has four sides. Therefore, pentagon is the correct answer.
12.
Tri means ___
Correct Answer
3
three
Explanation
The word "tri" is a prefix that means "three" or "having three." It is derived from the Latin word "tres" which also means "three." Therefore, the correct answer is 3 or three.
13.
Quad means _____
Correct Answer
4
four
Explanation
The word "quad" is a prefix derived from the Latin word "quattuor" which means "four". Therefore, "quad" is used to indicate the number four. In this context, "quad" means the number 4 or the word "four".
14.
Penta means ____
Correct Answer
5
five
Explanation
The word "penta" is derived from the Greek word "pente" which means "five". Therefore, "penta" is a term that represents the number 5. Additionally, "five" is the English translation of the word "penta".
15.
Hexa means _____
Correct Answer
6
six
