Chapter 2: Q3. (page 71)

Name or state the postulate, property, definition or theorem that justifies the statement.

If 鈭�AOBis a right angle, then OA鈫�鈯�OB鈫�, then 鈭�K鈮�鈭�M.

Short Answer

Expert verified

The property that justifies the statement is Property of Perpendicular Lines.

Step by step solution

01

Step 1. State the definition of perpendicular lines.

When two lines meet each other at right angles, they are called perpendicular lines.

02

Step 2. State the explanation.

When two sides make a right angle90鈭� with each other, then, both lines are perpendicular to each other.

Since, 鈭�AOB=90鈭�.

Therefore, OA鈫�鈯�OB鈫�.

This is the property of perpendicular lines.

03

Step 3. State the conclusion.

Therefore, the statement is justified by the property of perpendicular lines.
