Geometry help please! Match the reasons with the statements

Alex73 [517]

Given ⇔ 1. ∠PRS and ∠VUW are supplementary
Angles forming a linear pair sum of 180° ⇔ 3. ∠PRS + ∠SRU = 180°
Definition of Supplementary angle ⇔ 2. ∠PRS + ∠VUW = 180°
Transitive property of equality ⇔ 4 . ∠PRS + ∠VUW = ∠PRS + ∠SRU
Algebra ⇔ 5. ∠VUW = ∠SRU
Converse of Corresponding angle Postulate ⇔ Line TV || Line QS

Step-by-step explanation:

Here we have , ∠PRS and ∠VUW are supplementary . We need to complete the proof of TV || QS , with matching the reasons with statements .Let's do this :

Given ⇔ 1. ∠PRS and ∠VUW are supplementary
Angles forming a linear pair sum of 180° ⇔ 3. ∠PRS + ∠SRU = 180°
Definition of Supplementary angle ⇔ 2. ∠PRS + ∠VUW = 180°
Transitive property of equality ⇔ 4 . ∠PRS + ∠VUW = ∠PRS + ∠SRU
Algebra ⇔ 5. ∠VUW = ∠SRU
Converse of Corresponding angle Postulate ⇔ Line TV || Line QS

Above mentioned are , are the statements matched with expressions on right hand side (RHS) .

The Corresponding Angles Postulate states that, when two parallel lines are cut by a transversal , the resulting corresponding angles are congruent .

The converse states: If corresponding angles are congruent, then the lines cut by the transversal are parallel.

Moving a figure around a fixed point in the plane is called making a ___.

klasskru [66]

Answer:

Rotation.

Step-by-step explanation:

There are three rigid motions (which do not change the shape and size of the figures): rotation, translation and reflection.

You make a rotation of a figure when you turn it about a fixed point (which can be inside, on an edge or outside the figure) and it is measured in degrees. The rotation can be clockwise or counterclockwise.

What is the significance of a dashed and solid line on an inequality function?

Nadya [2.5K]

Answer:

Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.

Evaluate.

madreJ [45]

Answer:

Answer is none of these.

Answer is given below with explanations. 

Step-by-step explanation:

Given that x = -2.5

To find the value of x+13

Ob substituting the value in the given equation 

we get 

= -2.5+13

= 13 - 2.5 (we can also write like this)

= 10.5

Therefore value of x +13 is 10.5
