STAAR Angles and Triangles

2021

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

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

• The value of x is 180, because the labeled angles in each diagram are supplementary and the sum of the measures of supplementary angles is 180 degrees.

• The value of x is 90, because the labeled angles in each diagram are complementary and the sum of the measures of complementary angles is 90 degrees.

• The value of x is 44, because the sum of the measures of the labeled angles in each diagram is 180 degrees.

• The value of x is 136, because the labeled angles in each diagram are congruent.

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

Based on the diagrams, which statement is true?

• The value of x is 70, 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 are obtuse angles.

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

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

Based on these diagrams, which statement is true?

• The value of x should be 75, because the angles shown in the diagrams are congruent.

• The value of x should be 105, because the measures of the angles shown in the diagrams add up to 180°.

• The value of x should be 80, because the measures of the angles shown in the diagrams are both 70°.
