Check to see if the biconditional statement is true or false (show your work).
1. 1 and 2 are right angles if and only if 1 and 2 are supplementary.
2. Three lines are coplanar if and only if they are on the same plane

Answer 1

Statement 1 : False

Statement 2: True

Step-by-step explanation:

Statement 1 :

By definition ,

We know angles are said to be right angles if they are 90 degrees.

While on the other hand, angles are supplementary angles if they measure more than 90 degrees.

• Given 1 and 2 are right angles
• So they cannot be supplementary angles
• Proved statement is false

Statement 2 :

Co planar lines are lines that lie on same plane.

Hence lines are coplanar since they lie on same plane.

• True statement
