In a conditional statement, the independent part is the hypothesis and the dependent part is the conclusion.

In an if-then statement, the part of the statement immediately following 鈥渋f鈥� is the hypothesis, and the part of the statement immediately following 鈥渢hen鈥� is the conclusion.

The given statement is 鈥淭wo lines that are perpendicular form right angles鈥�.

The given statement has two parts, 鈥渢wo lines are perpendicular鈥� and 鈥渢hey form right angles鈥�.

Note that two lines forming a right angle depend on the line being perpendicular.

So, 鈥渢wo lines are perpendicular鈥� is the independent part of the statement and thus, the hypothesis. Similarly, 鈥渢hey form right angles鈥� is the dependent part of the statement and thus, the conclusion.

Write the hypothesis after 鈥渋f鈥� and conclusion after 鈥渢hen鈥� in an if-then statement to get:

鈥淚f two lines are perpendicular, then they form right angles.鈥�

This is the required if-then statement.
