What is a 120 angle?
< (less than) 90 degrees. 120. Obtuse. > (greater than) 90 degrees.
Is a 120 degree angle obtuse?
An obtuse angle is a type of angle whose degree measurement is more than 90° but less than 180°. Examples of obtuse angles are: 100°, 120°, 140°, 160°, 170°, etc.
How many 120 angles does it take to make a full turn?
There are 120 degrees in a third of a full turn. To determine this, you need to start with a full turn which is 360 degrees. If a full turn is 360 degrees, one-third of a full turn is 120 degrees since 360 divided by 3 is 120.
What is a 120 degree triangle called?
An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. Since, ∠A is 120 degrees, the sum of ∠B and ∠C will be less than 90° degrees.
Where is 120 degrees in protractor?
Read markings on the outer semicircle of the protractor and mark point G on 120°. Join F and G with the help of a ruler. We have ∠EFG = 120°.
What are 7 types of angles?
The rays making an angle are called the arms of an angle and the common end point is called the vertex of an angle. There are 7 types of angles. These are zero angle, acute angle, right angle, obtuse angle, straight angle, reflex angle, and complete angle.
What is the angle of obtuse?
Obtuse angles measure more than 90 degrees.
How many 90 angles does it take to make a full turn?
Answer: It takes eight 45 degree angles to make a full turn. Full turn means turning around until it points in the same direction again. Explanation: A full turn represents 360 degrees.
What angle is 45?
A 45-degree angle is exactly 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.
Can a triangle have an angle of 120 degrees?
An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. Here, the triangle ABC is an obtuse triangle, as ∠A measures more than 90 degrees. Since, ∠A is 120 degrees, the sum of ∠B and ∠C will be less than 90° degrees.
