What is a 170 degree angle called?

What is a 170 degree angle called?

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. ∠ PQR is an obtuse angle because it’s less than 180° and greater than 90°.

What is the opposite of 170 degrees?

The complement of −170° is the angle that when added to −170° forms a right angle (90° ).

What type of angle is 190 degrees?

acute angle-an angle between 0 and 90 degrees. right angle-an 90 degree angle. obtuse angle-an angle between 90 and 180 degrees.

Which is bigger a 180 degree angle or a 270 degree angle?

It is equal to one-quarter of a rotation around a circle. A straight line creates a 180 degree angle. It is equal to one-half a rotation around a circle. The larger angle at the intersection of a vertical and a horizontal line creates a 270 degree angle. It is equal to three-quarters of a rotation around a circle.

Which is the correct way to measure an angle?

Eg. ∠ABC, where B is the given angle. Angle measurement terms are – degree °, radians or gradians. The amount of rotation about the point of intersection of two planes (or lines) which is required to bring one in correspondence with the other is called an Angle.

How many 90 degree angles are there in a classroom?

Even in your classroom there are many 90 degree angles, like the corner of your desk and the corner of the board. To make 270 degrees, we would need to put together three 90 degree angles. If the entire circle were shaded, we would have gone 360 degrees.

How to isolate a from two supplementary angles?

To isolate a , divide both sides of the equation by 3 . So, the measures of the two supplementary angles are 60 ° and 120 ° . Find m ∠ P and m ∠ Q if ∠ P and ∠ Q are supplementary, m ∠ P = 2 x + 15 , and m ∠ Q = 5 x − 38 . The sum of the measures of two supplementary angles is 180 ° . Substitute 2 x + 15 for m ∠ P and 5 x − 38 for m ∠ Q .
