Constructing a 30 Degree Angle

What is the first step in constructing a 30-degree angle using a compass and straight edge?

• Construct a right triangle

• Draw a straight line

• Construct an equilateral triangle

• Draw a circle

How do you determine the third point of an equilateral triangle?

• By guessing its location

• By measuring with a ruler

• By swinging an arc from the first point

• By drawing a perpendicular line

What is the purpose of constructing a 60-degree angle in this process?

• To create a base for a square

• To use it as a reference for bisecting into a 30-degree angle

• To complete the triangle

• To measure the length of the sides

What is the next step after constructing a 60-degree angle to achieve a 30-degree angle?

• Draw a parallel line

• Use the angle bisector construction

• Extend the line further

• Measure the angle with a protractor

How can you verify that the constructed angle is 30 degrees?

• By ensuring the angle bisector divides the 60-degree angle equally

• By checking the length of the sides

• By measuring with a protractor

• By comparing it to a 45-degree angle
