## What does base mean in geometry?

bottom

In geometry, a base is a side of a polygon or a face of a polyhedron, particularly one oriented perpendicular to the direction in which height is measured, or on what is considered to be the “bottom” of the figure.

## How do you identify a base in geometry?

The base is the surface of the object that is stands on or it is the bottom line. Examples: The bottom of the triangular based prism is considered the base. The bottom line of the trapezoid can be considered the base.

**What is a base defined as?**

A base is a substance that can neutralize the acid by reacting with hydrogen ions. Most bases are minerals that react with acids to form water and salts. Bases include the oxides, hydroxides and carbonates of metals. The soluble bases are called alkalis. Sodium hydroxide is an alkali.

**What is the definition of a base of a triangle?**

Summary: The bottom line of a triangle is the base of the triangle, and it can be one of the three sides of the triangle.

### Is base the same as width?

Because the area of a rectangle is base times height (which is the same thing as length times width), and a triangle is half of a rectangle. Check out the above figure, which shows two triangles inscribed in rectangles HALF and PINT.

### How do you know the base of an object?

Substitute the value of “r” into the equation for the area of a circle: area = πr^2. Note that π is the symbol for pi, which is approximately 3.14. For example, a circle with a radius of 3 cm would yield an equation like this: area = π3^2. Simply the equation to determine the area of the base.

**How do you determine base?**

**Is base the same as length?**

Base is the length of one of the triangle’s sides, height is the distance from that side to the opposite corner of the triangle.

#### What makes a base a base?

A base is also defined as a molecule that has the ability to accept an electron pair bond by entering another atom’s valence shell through its possession of one electron pair. There are a limited number of elements that have atoms with the ability to provide a molecule with basic properties.

#### What is a base example?

Examples of bases are the hydroxides of the alkali and alkaline earth metals (sodium, calcium, etc.) and the water solutions of ammonia or its organic derivatives (amines). Such substances produce hydroxide ions (OH-) in water solutions (see Arrhenius theory).

**What is the definition of base in exponents?**

Usually, a power is represented with a base number and an exponent. The base number tells what number is being multiplied. The exponent, a small number written above and to the right of the base number, tells how many times the base number is being multiplied. For example, “6 to the 5th power” may be written as “65.”

**Is area and base the same thing?**

The area of a triangle is ½ (b × h), where b is the base and h is the height. The base of a triangle is any one of the sides, and the height of the triangle is the length of the altitude from the opposite vertex to that base.

## What does base area mean?

It refers to the area of one of the bases of a solid figure. It can be used to determine the volume of solid figures.

## What is a base area in math?

**Is base same as width?**

**Is the base and height of a triangle the same?**

The base of a triangle is any one of the sides, and the height of the triangle is the length of the altitude from the opposite vertex to that base.

### What is common in all bases?

All bases conduct electricity as they are good electrolytes. All bases turn red litmus paper into blue at the time of indication. Bases have a bitter taste with a soapy texture. Bases have a pH value of more than 7.

### What are properties of bases?

Chemical Properties of Bases

- Bases change the colour of litmus from red to blue.
- They are bitter in taste.
- Bases lose their basicity when mixed with acids.
- Bases react with acids to form salt and water.
- They can conduct electricity.
- Bases feel slippery or soapy.
- Some bases are great conductors of electricity.
