Introduction of Construction of Angles
We will study about Construction of Angles:
An angle is a figure formed by two rays, called the sides of the angle, that come together at a common point, called the vertex of the angle. The angle is measured in degrees, with 360 degrees in a full circle.
There are a few important things to know about angles:
- The two rays that form the angle are called its sides.
- The angle is measured in degrees, with 360 degrees in a full circle.
- The vertex of the angle is the point where the two rays meet.
- The angle can be right, acute, or obtuse, depending on how big the angle is.
Construction of Vertical Angles
Vertical angles are angles that are formed by two lines that intersect at a right angle. The vertical angles are equal in measure, and they are opposite each other.
Construction of Supplementary Angles
A supplementary angle is one that is formed when two lines intersect and the sum of their angles is greater than 180 degrees. To construct a supplementary angle, first draw a line and then use a protractor to measure the angle. Next, draw another line that intersects the first line and make sure that the angle is greater than 180 degrees. Finally, connect the two points to create the supplementary angle.
Construction – Step by Step Representation
This is a step by step representation of the construction of a simple house.
- The land is cleared and flattened.
- A foundation is laid, consisting of a frame of metal or wood beams and concrete.
- The frame is filled in with insulation, drywall, and electrical wiring.
- The roof is constructed, typically with shingles or tiles.
- Windows and doors are installed.
- Siding or cladding is added to the exterior.
- The final touches are made, such as adding a porch or a chimney.
Constructing 30, 60, 90, 120 Degree Angles
A 30-degree angle is a third of a circle. A 60-degree angle is two thirds of a circle. A 90-degree angle is a right angle. A 120-degree angle is a fourth of a circle.
