I'm being Timed please hurry. Triangle TUV is rotated as shown on the coordinate grid below, using the origin as the center of rotation. On a coordinate plane, triangle T U V has points (1, negative 2), (7, negative 2), (3, negative 3). Triangle T prime U prime V prime has points (2, negative 0.5), (6.2, 3.8), (4, 0). Which describes the rotation that took place?

A. a 90° clockwise rotation
B. a 90° counterclockwise rotation
C. 45° clockwise rotation
D. 45° counterclockwise rotation

D. 45 degree counterclockwise rotation

Step-by-step explanation: :              

The original image is triangle TUV and it has been rotated counter clockwise to form triangle T'U'V' using the origin as the center of rotation. . The rotation is 45 degrees rotation.                                

Hence, option B is correct.

687.09 dollars       happy now

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
