# Constructing the angle 75°?

Or simply:

- Set the 60 degree angle
- Perform angle addition construction of 60 to 30
- Perform an angle bisecting construction of the 30 degree angle
- Voila you have 75 degree angle

Bisecting angles twice will give an angle of 75°.

Construct an equilateral triangle using a compass. Each of the angles is 60°. Extend the base.

Now bisect the angle of 60° to create an angle of 30° inside the triangle. THe adjacent supplementary angle will be 150°,

Bisecting the angle of 150° will give the required angle of 75°.

To construct a 75° angle, follow these steps:

- Begin by drawing a straight line (referred to as the base line) using a ruler and pencil.
- Next, mark a point anywhere on the base line. This point will serve as the vertex of your angle.
- Using a protractor, align the center hole of the protractor with the vertex you marked on the base line.
- Then, rotate the protractor until the 0° line (or the horizontal line) aligns with the base line, ensuring that the protractor remains centered at the vertex.
- From the 0° mark on the protractor, counterclockwise, measure and mark 75° along the edge of the protractor.
- Draw a straight line from the vertex through the 75° mark you made on the protractor, extending it beyond the base line.
- Finally, use a ruler to draw a line segment from the vertex to where the line intersects the base line. This line segment forms a 75° angle with the base line.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
