Which relationships describe angles 1 and 2? Select each correct answer. Adjacent angles

Vertical angles

Complementary angles

Supplementary angles

They are adjacent angles and supplementary angles.

Step-by-step explanation:

∠1 and ∠2 are supplementary angles because they form a linear pair who sum = 180°

∠1 and ∠2 are adjacent angle because they are next to each other or you can say that they share a common side and have the same vertex.

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
