Failing mat
3) which angle is included between nm and pn? look at the first picture.

a) ∠nmn
b) ∠nmp
c) ∠mpn
d) ∠pnm

4) in the diagram, δmtd≅δslg. which statement is true. look at the second picture.

a) ∠t≅∠l
b)mt≅gl
c) td≅sg
d) ∠m≅∠g

5) what additional information is needed to prove the triangles are congruent by the sas postulate? look at the third picture.

a) ab≅ad
b)∠bac≅∠dac
c)∠cba≅cda
d)ab ⊥ ad

6) given ∠d≅∠t, ∠e≅∠u, de≅ut
name the postulate or theorem you can use to prove the triangles congruent. look at the fourth picture.

a) asa postulate

b)aas theorem

c)sss postulate

d)sas postulate

7) in δfkr, which side is included between ∠f and ∠r?

a) ar
b)∠k
c)rf
d)fk

8) in the paper airplane shown, abcd≅efgh, m∠b= m∠bcd= 90, m∠bad=125. find m
a) 125
b)65
c)55
d)90

3) D: The vertex, in this case N (as the middle point) needs to be in the middle of the name.

4) C: These triangles are reflection of each other, if you would place them in front of a mirror, this would be the only one true.

5) A: According to the picture, the angles are the same, so what will be missing is to know if the hypotenuse is the same, as we already know that one side is the same (perpendicular one), therefore we already have S(side), A (angle), missing side (S) for it to be solved by SAS.

6) A: ASA postulate says that you need one angle (A1), the side between A1 and A2, and a second angle (A2), which corresponds to tha description.

7) missing the picture

8) B: 65. Two of the angles are 90 and the other one is 125. Within any quadrilateral the sum of angles must be 360. Therefore m=360-90-90-125=65.

Step-by-step explanation:

4400

step-by-step explanation:

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
