What are internal collateral angles and external collateral angles?
Internal collateral angles: are the angles that are on the same side of the secant and within the lines. 2. External collateral angles: are those that are on the same side of the secant and outside the lines.
Why do the alternate exterior angles have the same measure?
Alternate exterior angles are the angles that, in a transversal line that separates two parallel lines, are visible to the parallel lines but alternate to the transversal. This is why they are equal angles and measure the same.
What angle do two parallel lines make?
– If the lines are coincident or parallel, the angle they form will be zero degrees. – If the lines are intersecting then the intersection point is the vertex of two angles, alternate-internal, we will keep the smaller of the two.
What are parallel lines cut by a transversal?
If a transversal line cuts two parallel lines: Alternate internal angles: are the angles that are between the parallel lines and on different sides of the transversal. Adjacent angles: are two angles that have a common vertex, a common side that separates them and the other two sides in a straight line.
How are the lines parallel?
Thus, two lines, contained in a plane, are parallel if they are either one and the same line (they are coincident lines) or, on the contrary, they do not share any point. Similarly, in space, two planes are parallel if they are one and the same plane or do not share any lines.
What are the characteristics of perpendiculars?
Two lines are perpendicular when they intersect to form four equal 90º angles. Two lines are perpendicular if their direction vectors are perpendicular. Given a Point belonging to a line or outside it, one and only one perpendicular to said Line passes through it.
What are the characteristics of graphical representations of parallel and perpendicular lines?
Parallel lines are coplanar lines that never intersect. In two dimensions, parallel lines have the same slope. they are parallel, since they both have a slope of 3. Perpendicular lines are lines that intersect at right angles.
What are the characteristics of graphic representations?
Characteristics: – The graphic representations allow us to visually and quickly discover, analyze and compare data on the evolution of one or several magnitudes, over time, in one or different places. – They facilitate the understanding of the facts and the relationships that exist between them.
How do you know if one line is parallel or perpendicular to another?
Identifying parallel or perpendicular lines
- Two lines that are parallel, their slopes are equal.
- Two lines are perpendicular to each other if the slope of one of the lines is reciprocal and has the opposite sign of the slope of the other line.
What are the characteristics of representations?
Origin: the subjects need representations to survive in the world. Functions: allow to act and understand. Elaboration: they are produced in response to the satisfaction of needs, they have their purpose in action and survival.
What are social representations and their characteristics?
The concept of social representation designates a form of specific knowledge, common sense knowledge, whose contents manifest the operation of socially characterized generative and functional processes. In a broader sense, it designates a form of social thought.
What is a rendering model?
First definition: a model is «a simplified representation of reality in which some of its properties appear» (Joly, 1988:111). Models are built to know or predict properties of the real object.
What is civil representation?
It is a legal figure by which what a person executes or celebrates on behalf of another, empowered by the person represented or designated by law to represent it, and that produces legal effects of that action in the patrimonial and legal sphere of the represented. …
What is a simplified representation?
The simplified rendering functionality allows you to do the following: Simplify the rendering of a design. It does this by displaying less detail by including or excluding features. Limit the representation of a design to a selected portion of the geometry of the total part.
Why do scientists work with models?
A scientific model is also a bridge to connect a scientific theory with a phenomenon, because it helps to develop the theory from the data and relates it to the natural world. The role of a model is to describe, explain and predict natural phenomena, as well as the communication of scientific ideas.
What do the economic models represent?
An economic model is a simplified representation of an economic process or phenomenon. An economic model is a simplified representation of the relationship between different variables that explain how the economy or a particular phenomenon of it operates.
