Quick Answer: How To Use A Protractor To Draw Angles?

How to Use a Protractor

Acute, obtuse, and right angles are the three types of angles. Acute angles are narrow (less than 90 degrees), obtuse angles are wide (greater than 90 degrees), and right angles are exactly 90 degrees (two lines perpendicular to each other).
Most protractors have two opposing ruler grids, one on each side of the arc and the other, making them useful for measuring angles originating from either direction. Draw the second leg of the angle using a ruler or another straight edge. The angle on a protractor will always be the same.

What is the first step in constructing an angle?

Construction: cut ABC in half.

  1. STEPS:
  2. Place the compass point on the angle’s vertex (point B).
  3. Stretch the compass to any length that will stay ON the angle.
  4. Swing an arc so the pencil crosses both sides (rays) of the given angle.

What angle is 45?

What is a 45-Degree Angle? A 45-degree angle is half of a 90-degree angle formed between two rays. It is an acute angle and two angles measuring 45 degrees from a right angle or a 90-degree angle.

What are the 7 types of angles?

Zero angle, acute angle, right angle, obtuse angle, straight angle, reflex angle, and complete angle are the seven types of angles.

What type of angle is 350 degrees?

Reflex angles are those with a degree measurement greater than 180 degrees but less than 360 degrees, such as 200 degrees, 220 degrees, 250 degrees, 300 degrees, 350 degrees, and so on.

What are the 5 types of angles?

Angles are classified as acute, right, obtuse, straight, or reflex.

  • Right angle
  • Obtuse angle
  • Straight angle
  • Reflex angle
  • Acute angle
  • Right angle
