Not every rectangle is a square, to be a square its sides must have the same length.
First one i think not positice
A slope also known as the gradient of a line is a number. The correct option is A, C, and D.
<h3>What is Slope?</h3>
A slope is also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.
For the given question,
- The temperature increased until 4:00 p.m.
This can be observed in the graph, as the slope of the graph before 4 pm is positive, it can be concluded that the temperature is increased until 4 pm.
- The temperature decreased after 6:00 p.m.
This can be observed in the graph, as the slope of the graph after 4 pm is negative, it can be concluded that the temperature is decreasing after 4 pm.
- The temperature increased more quickly between 12:00 p.m. and 4:00 p.m. than before 12:00 p.m.
This can be probed by calculating the slope of the line between the two points. Therefore, the slope between 8 am to 12 pm will be 1, while the slope from 12 pm to 4 pm will be equal to 4/3.
Hence, the correct option is A, C, and D.

The the next step in the proof is D. Statement: ∠7 ≅ ∠6 and ∠8 ≅ ∠5 Reason: Vertical Angles Theorem.
<h3>How to illustrate the angle?</h3>
It should be noted that vertical angles are the angles that are opposite each other when the two line cross.
In this case, 7 ≅ ∠6 and ∠8 ≅ ∠5 Reason: Vertical Angles Theorem.
In conclusion, the correct option is D.

Using translation concepts, we have that:
- For the translation, she has to communicate if it is up, down, left or right and the number of units.
- For a reflection she must communicate over which line the reflection happened.
<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
A translation is either shift left/right or bottom/up, hence she has to communicate if it is up, down, left or right and the number of units.
A reflection is over a line, hence she must communicate over which line the reflection happened.
