**Draw a number of lines at 30 degrees and then 'flip' the set square round to draw 30 degree lines in the opposite direction**. Draw a number of lines at 60 degrees and then 'flip' the set square round to draw 60 degree lines in the opposite direction. Adjustable set squares allow a range of angles to be drawn accurately.

In Geometry, it is important to know how to measure an angle. Using a protractor **helps us determine the angle measurement so we can label it as acute, right or obtuse**. Every protractor is a little bit different, but all will have a location on the bottom edge where we align the vertex of the angle we are measuring.

A set square or triangle (American English) is an object used in engineering and technical drawing, with the aim of **providing a straightedge at a right angle or other particular planar angle to a baseline**.

It's called **a corner**.

The instrument in the geometry box having the shape of a triangle are called **set-squares**. Was this answer helpful?

Most instruments are used within the field of geometry, including the **ruler, dividers, protractor, set square, compass, ellipsograph, T-square and opisometer**. Others are used in arithmetic (for example the abacus, slide rule and calculator) or in algebra (the integraph).

The geometry instrument box for kids has instruments like **compass, divider, protractor, set squares, half-length pencil** and more to help them achieve excellence in their class work.

**Properties of Emulsions**

- Emulsions contain both a dispersed phase and a dispersion medium.
- The boundary between the dispersion phase and dispersed medium is called “interface”.
- They have a cloudy appearance.
- They show various colors depending on the dilution.
- It shows the Tyndall effect.

5.3.1 Low-Pass Filter**The point at which frequencies stop getting passed and start getting attenuated** is known as the corner frequency. The corner frequency is the point where the output voltage is 70.7% of the input voltage ie. (0.707 × VIN ). This point is sometimes called the 'cutoff frequency' or the '-3dB' point.

Although oil and water can't mix, we can break oil down into teeny-tiny droplets that can remain suspended in the water. An emulsion happens **when small droplets of one solution (the dispersed solution, which is often oil based) are dispersed throughout another** (the continuous solution, which is often water based).

emulsion, in physical chemistry, **mixture of two or more liquids in which one is present as droplets, of microscopic or ultramicroscopic size, distributed throughout the other**.

Emulsion – **A solution of two immiscible liquids that have been forcefully mixed together**.

Solution. **That particular frequency of incident radiation for which the minimum negative potential V _{0} given to a plate for photelectric current becomes zero** is called the cut-off frequency.

Emulsions are **colloidal solutions with both dispersed phase and dispersion medium being liquid**. Thus, finely divided droplets of one liquid are dispersed in another medium. Emulsions can be formed from any two immiscible liquids. Two types of emulsions include oil in water emulsion and water in oil emulsion.

**To find the cutoff frequency for a high pass RL filter, proceed as follows:**

- Multiply the inductance value ( L ) with 2π .
- Divide the resistance ( R ) by the value from step 1.
- You have determined the cutoff frequency of the high pass RL filter.

An emulsifier or emulsifying agent is **a compound or substance that acts as a stabilizer for emulsions, preventing liquids that ordinarily don't mix from separating**. The word comes from the Latin word meaning "to milk," in reference to milk as an emulsion of water and fat. Another word for an emulsifier is an emulgent.

In an emulsion, one liquid (the dispersed phase) is dispersed in the other (the continuous phase). Examples of emulsions include **vinaigrettes, homogenized milk, liquid biomolecular condensates, and some cutting fluids for metal working**.
