 Question 1: Inductive Reasoning

1.1. Using only a straightedge and reasoning, try to make the angles with the measures below.
Then describe your reasoning process. After making each angle, check your work using a
protractor and determine the percentage error.

A) 30°

Reasoning Process:
 First, construct a straight angle (180°) using a straight line.
 Then, estimate a 90° angle (a right angle), which is a quarter-turn.
 Divide that 90° angle into three equal parts. Each part is approximately 30°.
 Construct one of those divisions.

Check:
 Use a protractor to measure the constructed angle.
 Suppose the measured angle is 28°.

Percentage Error:




B) 45°

Reasoning Process:
 Construct a 90° angle.
 Bisect it (divide into 2 equal parts) using your straightedge and logical estimation.
 Each part is 45°.

Check:
 If your protractor shows 46°:

Percentage Error:
