right angle
obtuse angle
line

Answer 1

Answer;

-Line

Two adjacent, supplementary angles form a straight line

Explanation;

• Supplementary angles are those angles whose sum add up to 180 degrees. Thus, two angles are said to be supplementary if their sum adds up to 180 degrees.
• Similarly, angles on a straight line add up to 180 degrees, which means they are supplementary angles.
• Thus, two adjacent supplementary angles add up to 180 and it means they are on a straight line.
