Why studying history is a waste of time?

Why studying history is a waste of time?

Most people memorise dates, names and facts when they study history. This information is not useful in everyday life or for the future. For this reason, it makes learning history a waste of time because events can also be interpreted in a different way which makes what we learn in history less valuable.

Should we study history Why or why not?

Studying history helps us understand and grapple with complex questions and dilemmas by examining how the past has shaped (and continues to shape) global, national, and local relationships between societies and people.

Why is studying history important?

Studying history allows us to observe and understand how people and societies behaved. For example, we are able to evaluate war, even when a nation is at peace, by looking back at previous events. History provides us with the data that is used to create laws, or theories about various aspects of society.

Why is it important to look back at the past?

It’s important to honor our past and pass it on. Looking back on the past allows us to study the nature of ourselves and helps us recognize why we do what we do. It’s important not look too much into the past or keep your mind there for too long – you can easily get trapped there.

What does it mean to reflect in math?

A reflection is a transformation representing a flip of a figure. Figures may be reflected in a point, a line, or a plane. When reflecting a figure in a line or in a point, the image is congruent to the preimage. A reflection maps every point of a figure to an image across a fixed line.

Which statement is true reflection?

Answer Expert Verified Answer: *An image created by a reflection will always be congruent to its pre-image. *Corresponding angles and segments are always congruent in a reflection of a figure. *An image and its pre-image are always the same distance from the line of reflection.

Which statements must be true about the image of Δmnp after a reflection across line EG?

Answer. Answer: The image will be congruent to ΔMNP. The orientation of the image will be the same as the orientation of ΔMNP. The line segments connecting corresponding vertices will all be parallel to each other.

What is the rule for the reflection Brainly?

Answer Expert Verified The figure is being reflected over the x axis (horizontal axis). Any y coordinate that is negative becomes positive, and vice versa. The x coordinate stays the same. If we have some point (x,y) as the original point, then it would turn into (x,-y).

Which statements must be true about the image of MNP after a reflection?

Answer: The image will be congruent to ΔMNP. Line EG will be perpendicular to the line segments connecting the corresponding vertices.

Which segment is the image of AB reflected across the line y =- 2?

Answer: The line segment GH is the answer. Step-by-step explanation: In the given figure we can see that point B of line AB lies one unit below the given y=-2.

Which point would map onto itself after a?

Answer:the answer is the point (-4,0),this point would map into itself when reflected in the line y= – x, this is because the point (-4,0) is in the line y= – x thus it will map onto itself when reflected as it is in touch with the mirror line which is the line y= – x.

What is the line of reflection for the trapezoid?

Reflection Symmetry in Trapezoids An isosceles trapezoid will have reflection symmetry because the line connecting the midpoints of the bases will be a line of symmetry.

Which point would map onto itself?

In order for the figure to map onto itself, the line of reflection must go through the center point. Two lines of reflection go through the sides of the figure. Two lines of reflection go through the vertices of the figure. Thus, there are four possible lines that go through the center and are lines of reflections.

At which angle will the hexagon rotate onto itself 60?

A hexagon has six angles. A full circle is 360°; since there are 6 angles in the hexagon, it will rotate onto itself every 360/6 = 60°. This means that the hexagon will rotate onto itself at angles that are multiples of 60°; this means that 120° and 180° will also do this.

Which point would map onto itself after a reflection across the line y Brainly?

Any point which maps on to itself across this line will have to lie on the line.

Which triangle must be a right triangle and why ΔA B C is right because it is the image of Δabc?

ΔA’B’C’ is right because it is the image of ΔABC. ΔADC is right because AA’ intersects AC at A. ΔBCC’ is right because B lies of the line of reflection. ΔBGC is right because Line E G is perpendicular-to CC’.

Which triangle must be a right triangle and why?

Answer: Right triangles are triangles in which one of the interior angles is 90 degrees, a right angle. Since the three interior angles of a triangle add up to 180 degrees, in a right triangle, since one angle is always 90 degrees, the other two must always add up to 90 degrees (they are complementary).

Which could be coordinates of D o g after the reflection?

Answer Expert Verified The coordinates of D’O’G’ after the reflection would be D=(0,0), O=(-1,2), G=(1,4).

Which sequence of transformations produces an image that is not congruent?

Dilation, by its nature, changes the size of the object, so the result is NOT congruent to the original. Choice D includes dilation, so the image is not congruent to the original.
