Revolt · Accepted Answer

64°

Question 2

On a coordinate plane, 2 lines are shown. Line A B has points (negative 4, negative 2) and (4, 4). Line C D has points (0, negative 3) and (4, 0).

Revolt · Accepted Answer

Question 4

Triangle A B C is shown. Lines are drawn from each point to to the opposite side and intersect at point G. Line segments A D, B E, and C F are created.

Revolt · Accepted Answer

Point G can be the centroid because 12:6 equals 2:1.

Question 5

Triangle DEF was tranformed to create triangle D'E'F'. Complete the statement about the transformation.

Revolt · Accepted Answer

point E.

Question 6

On a coordinate plane, a line goes through (negative 3, 3) and (negative 2, 1). A point is at (4, 1).

Revolt · Accepted Answer

y − 1 = −2(x − 4)

Question 7

Triangle B C D is shown. Line D B extends through point A to form exterior angle A B C. Angle B D C is 67 degrees and Angle C D B is 60 degrees.

Revolt · Accepted Answer

m∠ABC = 127°

Question 8

Two parallel lines are crossed by a transversal.

Revolt · Accepted Answer

g = 105

Question 9
