Staar Triangles

Four triangles are shown. One side of each triangle lies on a ray, and the triangles are not drawn to scale.

Based on the triangles, which statement about x is true?

• x = 160, because 180 - (130+30) = 20 and 180 - 20 = 160

• x = 20, because 130 + 30 = 160 and 180 - 160 = 20

• x = 80, because 180 - 130 = 50 and 50 + 30 = 80

• x = 340, because 130 + 30 = 160 and 160 + 180 = 340

Based on these triangles, which statement is true?

• w = 75, because 45 + 60 = 105 and 180 - 105 = 75

• w = 105, because 180 - (45 + 60) = 75 and 180 - 75 = 105

• w = 285, because 45 + 60 = 105 and 105 + 180 = 285

• w = 165, because 180 - 60 = 120 and 120 + 45 = 165

Which statement is true?

• The relationship between the slope of the line DF and the slope of line GI cannot be determined

• The slope of line DF is greater than the slope of line GI

• The slope of line DF is less than the slope of line GI

• The slope of line DF is equal to the slope of line GI
