If S equals straight lines in the plane and ab if a and b are parallel Verify that the relation is an equivalence relation on the set S given?
Establishing equivalence depends on the definition of parallel lines. If they are defined as lines which cannot ever meet (have no point in common), then the relation is not reflexive and so cannot be an equivalence relation.
However, if the lines are in a coordinate plane and parallel lines are defined as those which have the same gradient then:
- the gradient of a is the gradient of a so the relationship is reflexive ie a ~ a.
- if the gradient of a is m then b is parallel to a if gradient of b = m and, if the gradient of b is m then b is parallel to a. Thus the relation ship is symmetric ie a ~ b <=> b ~ a.
- If the gradient of a is m then b is parallel to a if and only if gradient of b = gradient of a, which is m. Also c is parallel to b if and only if gradient of c = gradient of b which is m. Therefore c is parallel to a. Thus the relation is transitive, that is a ~ b and b ~ c => a ~ c.
The relation is reflexive, symmetric and transitive and therefore it is an equivalence relationship.

Verify that the straight line joining mid -point of any two sides of triangle is parallel to the third side and equal to half of it?
Input straight line joining mid -point of any two sides of triangle is parallel to the 3rd side and equal to half of it.
When constructing parallel lines how can you be sure the lines you constructed are parallel?
To ensure the lines you constructed are parallel, you can use a ruler or straightedge to measure the distance between the lines at multiple points; if the distance remains consistent, the lines are parallel. Alternatively, you can use a protractor to verify that corresponding angles formed by a transversal intersecting the lines are equal. Lastly, using a compass to create equal distances from a reference point to both lines can also confirm their parallelism.
Which transformation can verify congruence by sliding one triangle over another apex?
The transformation that can verify congruence by sliding one triangle over another is called a translation. During this transformation, one triangle is moved (or "slid") along a straight path without rotating or flipping it, allowing for direct comparison of corresponding sides and angles. If the triangles align perfectly after the translation, it confirms that they are congruent.
What is the noun form of the verb verify?
The noun forms of the verb to verify are verifier, verification, and the gerund, verifying.
How do you use the word verification in a sentence?

How far Ohm's Law is verified for series and parallel circuit?
You cannot 'verify' Ohm's Law with a series or parallel circuit. The only way of verifying Ohm's Law is to plot a graph of current against voltage for variations in voltage. If the resulting graph is a straight line, then you have verified Ohm's Law for the load you have used.
How will you Verify that the set of all straight lines under the relationparallel to is an equivalence relation?
Suppose S is a set of all lines.Then for any line s in S, s s (reflexive);For any two lines s and t in S, s t if and only if t s (symmetric);For any three line, s, t and u in S, s t and t u => s u.Each of these statements are easy to prove if you use the slope-intercept or standard form of the lines' equations.
Ranger wants to verify that the expression8x – 20 is the correct simplified expression for 4(2x – 5). Explain how to verify the simplified expression?
Sample Answer: To verify, a number needs to be substituted for x in both expressions. Use order of operations to simplify and find the value. The value needs to be the same for both expressions to prove equivalence.
Is it possible that there are parallel universes which form the multiverse?
It is entirely possible, but difficult to verify, one way or the other.
What is the best way to wire your subs to get the most power?
You get more power by wiring the speakers in parallel, but you need to verify that the amplifier can handle that configuration or you may blow the amp.
How can you verify the verticality of an object using a piece of string with a weight on the end?
For this hammer a nail very close to the object into the object and hang the string on that nail. Then let the string with weight stop swinging (best to do it in an enclosed room with no wind). When the string stops swinging, if the straight-edged object is parallel with the string, then the object is completely vertical
When constructing parallel lines how can you be sure the lines you constructed are parallel?

The total resistance of a circuit with three 30 ohm resistors in parallel is ohms?
If the parallel resistors are equal, then the total resistance (in this case, with three resistors) will decrease by a factor of 3. I suggest you verify this with the standard formula for parallel resistance: 1/R = 1/R1 + 1/R2 + 1/R3, replacing the value 30 for R1, R2, and R3, and calculating R, the combined resistance.
Is this a reliable resource for an academic paper?
hell no. If i saw this site as reference in an academic paper i would no be happy it's like using straight wikipedia. you can't even verify who is writing it.
Is the vitamin shoppe a safe place to purchase medication?
Yes it is and it is stated within their Terms of Service agreement. You can simply call them or even fax them to have them verify it straight to you if you need added proof.
Are the graphs of 2x plus 7y equals 6 and 7y equals 2x plus 6 parallel?
Yes, they are. If you solve 2x + 7y = 6 for y, you get y = (-2x + 6) / 7. If you solve 7y + 2x + 6 = 0 for y, you get y = (-2x - 6) / 7. As you can see, both equations have the same slope. Therefore they are parallel. You can punch those equations into a graphing calculator and visually verify that they are indeed parallel.
