What is an object measured in three dimensions of length, width, and height?
Correct Answer
C. Three-Dimensional.
Explanation
An object measured in three dimensions of length, width, and height is referred to as three-dimensional. This means that the object has a physical presence and occupies space in three different directions. The dimensions of length, width, and height provide a comprehensive description of the object's size and shape, allowing us to visualize it in a three-dimensional space.
2.
What is a polygon with four sides called?
Correct Answer
C. Quadrilateral.
Explanation
A polygon with four sides is called a quadrilateral. A quadrilateral is a polygon that has four straight sides and four angles. The term "quad" refers to the number four, and "lateral" refers to sides. Therefore, a quadrilateral is a geometric shape that consists of four sides.
3.
What is the amount left over when a number can't be divided equally?
Correct Answer
C. Remainder.
Explanation
When a number cannot be divided equally, the amount left over is called the remainder. This means that there is a remainder or leftover amount after dividing the number by another number. For example, if we divide 10 by 3, the quotient is 3 with a remainder of 1. So, in this case, the correct answer is "Remainder".
4.
How many sides of the same length does a rhombus have?
Correct Answer
D. Four.
Explanation
A rhombus is a quadrilateral with four sides of equal length. Therefore, it has four sides of the same length.
5.
What is the part of a line that has an endpoint and runs in one direction?
Correct Answer
B. Ray.
Explanation
A ray is a part of a line that has one endpoint and extends infinitely in one direction. It can be thought of as a beam of light emanating from a point and continuing indefinitely. In contrast, a line segment has two endpoints and a definite length, whereas a ray has no specific length. Therefore, the correct answer is ray.
6.
What kind of clock has hands moving on it for showing hours and minutes?
Correct Answer
D. Analog.
Explanation
An analog clock is a type of clock that has hands moving on it to show hours and minutes. This type of clock typically has a circular face with numbers or markers around the edge to indicate the hours, and the hands rotate around the center of the clock to show the current time. Stopwatch, sundial, and digital clocks do not have hands moving on them to show hours and minutes, making analog the correct answer.
7.
What is 10 - 4 equal to?
Correct Answer
D. 6
Explanation
The correct answer is 6 because when you subtract 4 from 10, you are left with 6.
8.
What is the line segment where two faces of a solid figure meet?
Correct Answer
D. Edge.
Explanation
An edge is the line segment where two faces of a solid figure meet. It is the boundary between two adjacent faces and represents the intersection of these faces. In other words, it is the line that connects two vertices of a solid figure. In this context, the other options are not relevant. A surface refers to the outer layer of a solid figure, a vertex represents a point where multiple edges meet, and a diameter is a line segment that passes through the center of a circle or sphere.
9.
In which direction(s) does a plane extend?
Correct Answer
B. In All Directions.
Explanation
A plane extends in all directions because it is a two-dimensional surface that has length and width but no depth. It can be thought of as an infinitely large flat surface that continues indefinitely in all directions. Therefore, it extends both horizontally (left to right and right to left) and vertically (up and down).
10.
What is a "point"?
Correct Answer
D. An Exact Location In Space.
Explanation
The term "point" refers to an exact location in space. In geometry, a point is a fundamental concept that has no size or dimension, but represents a specific position. It is often denoted by a dot and can be used to describe the location of objects or define geometric shapes. In other contexts, "point" can also refer to a particular spot or position in various fields such as navigation, mapping, or even in a conversation.
11.
Which unit is used to measure angles or temperatures?
Correct Answer
C. Degree.
Explanation
The unit used to measure angles or temperatures is called a degree. This unit is commonly used in mathematics, physics, and meteorology to quantify the size or amount of rotation or inclination. It is denoted by the symbol ° and is divided into smaller units such as minutes (') and seconds ("). The other options, inch, decimeter, and point, are not used to measure angles or temperatures.
12.
If two objects have the same shape, but are different in size, then they are what?
Correct Answer
C. Similar.
Explanation
If two objects have the same shape but are different in size, they are considered similar. Similarity refers to when two or more objects have the same shape, but their sizes may vary. In this case, the objects may have different dimensions or proportions, but their overall shape remains the same. The term "similar" is commonly used in geometry to describe objects that have the same shape but are not necessarily identical in size.
13.
How many right angles does a square have?
Correct Answer
A. 4
Explanation
A square has four right angles because all four of its sides are equal in length and each corner forms a 90-degree angle. This is a defining characteristic of a square, as it distinguishes it from other shapes that may have different angles. Therefore, the correct answer is 4.
14.
In an expression, what is missing?
Correct Answer
B. An Equal Sign.
Explanation
The given correct answer is "An Equal Sign." In an expression, an equal sign is used to indicate that both sides of the equation are equal. Without an equal sign, the expression would not represent an equation but rather a statement or a mathematical operation. The presence of an equal sign is crucial in expressing mathematical relationships and solving equations.
15.
Which triangle has three congruent sides?
Correct Answer
C. Equilateral.
Explanation
An equilateral triangle is the only type of triangle that has three congruent sides. Uneven, double, and right triangles do not have all sides congruent.
