As you solve test items, you must understand the meanings of mathematical terms. Choose the correct term to complete each sentence.
- Two lines that intersect to form right angles are (parallel, perpendicular) lines.
- A quadrilateral with two pairs of adjacent sides congruent and no opposite sides congruent is called a (rhombus, kite).
- The (circumcenter, incenter) of a triangle is the point of concurrency of the perpendicular bisectors of the sides of the triangle.
- Two angles are (complementary, supplementary) angles if the sum of their measures is 90.
- In a plane, two lines that never intersect are (parallel, skew) lines.
