What is the reference angle of 450 degrees?
Subtract 360° 360 ° from 450° 450 ° . The resulting angle of 90° 90 ° is positive, less than 360° 360 ° , and coterminal with 450° 450 ° .
What is the Coterminal angle of 420 degrees?
Subtract 360° 360 ° from 420° 420 ° . The resulting angle of 60° 60 ° is positive, less than 360° 360 ° , and coterminal with 420° 420 ° .
What are the Coterminal angles of 500 degrees?
Subtract 360° 360 ° from 500° 500 ° . The resulting angle of 140° 140 ° is positive, less than 360° 360 ° , and coterminal with 500° 500 ° .
What is the angle of 120 degree called?
Obtuse Angle Measure = (180 – acute angle measure) In the picture above, line segment DO intersects line segment OQ at point O and forms an angle DOQ measuring 120°. Thus, it is an obtuse angle.
Can angles be 0 degrees?
A zero angle (0°) is an angle formed when both the angle’s arms are at the same position. An acute angle is an angle that is more than 0° but less than 90°. Common examples of acute angles include: 15°, 30°, 45°, 60°, etc.
What does a 1 degree angle look like?
An angle that turns through 1/360 of a circle is called a “one-degree angle,” and can be used to measure angles; An angle that turns through n one-degree angles is said to have an angle measure of n degrees.
Is 360 degrees an angle?
A 180° angle is called a straight angle. Angles such as 270 degrees which are more than 180 but less than 360 degrees are called reflex angles. A 360° angle is called a complete angle.
Is 45 degrees an acute angle?
Acute angle. It’s any angle that measures more than 0 degrees but less than 90 degrees. An acute angle falls somewhere between nonexistent and a right angle (see Figure 4). Figure 4: Acute angles — at 45° (Figure a), 60° (Figure b), and 30° (Figure c).
What is the longest side of TUV?
Triangles IJK and TUV are similar. The length of the sides of IJK are 203, 154 and 196. Then length of the longest side of TUV is 348….
What is the smallest side of a triangle?
In such a triangle, the shortest side is always opposite the smallest angle. (These are shown in bold color above) Similarly, the longest side is opposite the largest angle. In the figure above, drag any vertex of the triangle and see that whichever side is the shortest, the opposite angle is also the smallest.
How do you find an angle from smallest to largest?
So, if given three side lengths, in order to put the angles in order from smallest to largest, first find the smallest angle by finding the angle opposite the smallest side, then, the medium-sized angle by finding the angle opposite the medium-sized side, and the largest angle opposite the largest side.
