Which type of lines intersect and form right angles?

• parallel

• horizontal

• perpendicular

• vertical

Lines that are in the same plane but never intersect are called ​ (a)   ​

• parallel
• Broadway
• perpendicular
• transversals

When the lines are parallel, corresponding angles have to be​ (a)  

• congruent
• supplementary
• adjacent

Answer explanation

Vertical angles are always congruent, and linear pairs are​ (a)  

• supplementary
• complementary
• acute

Given parallel lines cut by a transversal, which angle pairs will be congruent?

• linear pairs

• vertical angles

• corresponding angles

• adjacent angles
