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 do you draw a 160 degree angle without a protractor?

step 1 : draw a long straight line in your drawing paper. step 2 : set a definite arc in your compass and draw half circle as shown in figure. step 3 : using compass, cut two points C and D on semi circle. step 4 : from point D, cut an arc on E as shown in figure.

What angle is 89 degrees?

Since acute angles are angles with a measure less than 90°, the largest integer acute angle will have a measure of 89°.

What is special about angles that add up to 160?

Hence, one angle is 20 degrees, and the other is 160 degrees. Therefore, the angles 20 degrees and 160 degrees are the two supplementary angles.

What type of angle is a 165 angle?

An acute angle is an angle with a measure of less than 90 degrees. An obtuse angle is an angle greater than 90 degrees but less than 180 degrees.

Is 180 degrees an angle?

Angles that are 180 degrees (θ = 180°) are known as straight angles.

How do you construct a 165 degree angle with a compass and a ruler?

Steps of Construction:
1.Construct a line segment BC.2.Taking B as centre and some suitable radius construct an arc which meets BC at the point P.3.Taking P as centre and same radius cut off arcs at PQ,QR and then RS.4.Now join SB.

What is the name of 270 degree angle?

A 270-degree angle is called a reflex angle because it is greater than a straight angle or 180° and less than a complete angle (360 degrees).

What is the angle of 45 degrees?

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 form a right angle or a 90-degree angle. We know that an angle is formed when two rays meet at a vertex.

What is in obtuse angle?

Obtuse angles measure more than 90 degrees.

What do supplementary angles add up to?

A and ( Another Angle ) Since they are supplementary, they add up to 180 degrees.

Can 2 acute angles be supplementary?

Thus, the two acute angles cannot be supplementary angles. Thus, two right angles are supplementary angles.
