STAAR geometry

In each diagram, line k is parallel to line l, and t intersects lines k and l.

Based on the diagrams, which statement is true?

• The value of x is 79, because the two angles shown in each diagram are congruent.

• The value of x is 101, because the two angles shown in each diagram are supplementary.

• The value of x is greater than 90, because the two angles shown in each diagram obtuse angles.

• The value of x is 11, because the two angles shown in each diagram are complementary.

Four triangles are shown.

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

In each diagram, line p is parallel to line f, and t intersects lines p and f.

Based on the diagrams, which statement is true?

• The value of x is 75, because the two angles shown in each diagram are congruent.

• The value of x is 105, because the two angles shown in each diagram add up to 180°.

• The value of x should be 140, because the measures of the angles shown in the diagrams should add up to 360 and 360 - (110 + 110) = 140.

• The value of x is 70, because the two angles shown in each diagram are both 70°.
