**9. Hect-**: Hect- is a prefix derived from the Greek word “hecto,” meaning one hundred. In the metric system, it denotes multiplication by 100.

**10. Hectagon**: A hectagon is a polygon with 100 sides. It is a rare geometric shape, and regular hectagons have interior angles of 176.4 degrees.

**11. Hectares**: Hectares are a unit of area measurement commonly used to describe large land areas, such as farms and estates. One hectare is equal to 10,000 square meters.

**12. Heft**: Heft refers to the weight or heaviness of an object. In mathematical contexts, it might be used more metaphorically, but understanding the heft of numbers is essential in certain calculations.

**13. Height**: Height refers to the measurement of how tall an object is, typically perpendicular to the base. It plays a vital role in geometry and is used to determine areas and volumes of various shapes.

**14. Height of Equilateral Triangle**: In an equilateral triangle, the height is the perpendicular distance from any vertex to the opposite side. In this special type of triangle, all three sides are equal, and the height divides the base into two equal segments.

**15. Helix**: A helix is a three-dimensional curve that resembles a spring or coil. It can be formed by moving a point at a constant angle and a constant rate around a central axis.

**16. Hemisphere**: A hemisphere is a three-dimensional shape resembling half of a sphere. It is formed by cutting a sphere into two equal parts along a plane.

**17. Hemisphere Shape**: The hemisphere shape finds its application in various fields, such as architecture, astronomy, and biology. For example, human brains can be roughly approximated as hemispheres.

**18. Hendecagon**: A hendecagon is an 11-sided polygon. In a regular hendecagon, all sides and angles are equal, making it a unique and fascinating geometric figure.

**19. Hepta-**: Hepta- is a prefix derived from the Greek word “heptá,” meaning seven. In the metric system, it denotes multiplication by seven.

**20. Heptagon**: A heptagon is a seven-sided polygon. In a regular heptagon, all sides and angles are equal, making it an intriguing geometric shape.

**21. Hexa-**: Hexa- is a prefix derived from the Greek word “hex,” meaning six. In the metric system, it denotes multiplication by six.

**22. Hexadecimal**: Hexadecimal is a base-16 number system used in computing and digital electronics. It includes digits from 0 to 9 and letters from A to F, representing values from 0 to 15.

**23. Hexadecimal Number**: A hexadecimal number is a number expressed in base-16 using the hexadecimal digits.

**24. Hexagon**: A hexagon is a six-sided polygon. It is a commonly occurring shape in nature and art due to its balance and symmetry.

**25. Hexagonal Prism**: A hexagonal prism is a three-dimensional shape with hexagonal bases and rectangular sides. It is a type of prism and finds applications in geometry and architecture.

**26. Hexahedron**: A hexahedron is a three-dimensional shape with six faces. It is a broader term that includes cubes as well.

**27. Highest Common Factor**: The Highest Common Factor (HCF) is the largest number that divides two or more integers without leaving any remainder. It is a crucial concept in number theory and plays a vital role in simplifying fractions and solving equations.

**28. Hindu-Arabic Number System**: The Hindu-Arabic number system, also known as the decimal system, is the most widely used numeral system in the world today. It uses ten digits (0 to 9) to represent all numbers.

**29. Histogram**: A histogram is a graphical representation of the distribution of data. It consists of bars, where each bar represents a range of data and the height of the bar corresponds to the frequency of data within that range.

**30. Horizontal**: Horizontal refers to the direction parallel to the horizon or the base. In Cartesian coordinates, the x-axis is horizontal.

**31. Horizontal Bar Graph**: A horizontal bar graph is a type of graph where the bars are represented horizontally along the y-axis. It is useful for comparing data between different categories.

**32. Horizontal Flip**: A horizontal flip is a transformation that reflects an object or shape across a horizontal line. It results in a mirror image of the original object.

**33. Hour**: An hour is a unit of time equal to 60 minutes or 1/24th of a day. It is a fundamental unit for measuring time in various systems.

**34. Hour Hand**: The hour hand is the shorter hand on a clock that points to the hour of the day. It rotates around the clock’s center, indicating the current hour.

**35. Hundred**: A hundred is a numerical value equal to 100. It is the square of 10 and plays a significant role in counting and place value.

**36. Hundredth**: A hundredth is a fraction equal to 1/100. It is used to express very small quantities or percentages.

**37. Hyperbola**: A hyperbola is a type of conic section characterized by its eccentric shape. It consists of two separate curves that mirror each other.

**38. Hyperbolic Functions**: Hyperbolic functions are a set of mathematical functions that resemble trigonometric functions but are defined using the hyperbola.

**39. Hypercube**: A hypercube is a generalization of a cube to higher dimensions. In a three-dimensional space, it becomes a cube, and in four dimensions, it becomes a hypercube.

**40. Hypocycloid**: A hypocycloid is a curve traced by a fixed point on the circumference of a smaller circle as it rolls inside a larger circle without slipping.

**41. Hypotenuse**: In a right triangle, the hypotenuse is the side opposite the right angle. It is the longest side and is related to the other two sides by the Pythagorean theorem.

**42. Hypotenuse in Right Triangle**: The length of the hypotenuse can be calculated using the Pythagorean theorem, which states that the square of the hypotenuse’s length is equal to the sum of the squares of the other two sides.

**43. Hypothesis**: In mathematics, a hypothesis is a proposition or statement that is assumed to be true for the purpose of reasoning or research. It serves as a starting point for investigations and further analysis.
