What are the measure of angles?
An acute angle is lower than 90 degrees. An obtuse angle is higher than 90 degrees. But lower than 180 degrees. A right angle is exactly 90 degrees. A straight angle is exactly 180 degrees. A reflex angle is higher than 180 degrees. A Circle is exactly 360 degrees.
Does obtuse triangle have a right angle?
No, an obtuse triangle cannot have a right triangle for the reason that an obtuse angle is greater than 90 degrees; therefore, the other two angles must be lower than 90 degrees.
Is a acute a 53 degree angle?
90 degrees is a right angle lower than 90 is an acute angle higher than 90 but less than 180 is an obtuse angle 180 is a line Greater than 180 is a reflex angle
How many degrees does there have to be in an obtuse angle?
Over 90 but under 180 degrees. any lower is a right angle or acute angle, and higher is a straight line or a reflex angle.
What is the measure of and obtuse angle and acute angle?
An obtuse angle is anything that measures between 91-179 degrees. (because 90 degrees is a right angle and 180 is a straight angle) An acute angle is anything that is lower than 90 degrees.** TIP: I remember acute angles because it has the word cute in it and I think "Oh it's so cute." I can remember right angles because "They are always right, proper, and tall." Straight angles look like a straight line so that's easy enough to remember.
What is a measure for an acute angle?
An acute angle is 89 degrees or lower.
What is an angle that measures is greater than 90 degrees but lower than 180 degrees?
An angle that measures greater than 90 degrees but less than 180 degrees is an obtuse angle.
What is the measure ment of a acute angle?
The measure is lower than 90 degrees.
What are the measure of angles?
An acute angle is lower than 90 degrees. An obtuse angle is higher than 90 degrees. But lower than 180 degrees. A right angle is exactly 90 degrees. A straight angle is exactly 180 degrees. A reflex angle is higher than 180 degrees. A Circle is exactly 360 degrees.
How much does a acute angle measure?
an acute angle doesn't have an exact measurement, but it is lower than 90 degrees. So any angle below 90 degrees is an acute.
Does obtuse triangle have a right angle?
No, an obtuse triangle cannot have a right triangle for the reason that an obtuse angle is greater than 90 degrees; therefore, the other two angles must be lower than 90 degrees.
Is a acute a 53 degree angle?
90 degrees is a right angle lower than 90 is an acute angle higher than 90 but less than 180 is an obtuse angle 180 is a line Greater than 180 is a reflex angle
How many degrees does there have to be in an obtuse angle?
Over 90 but under 180 degrees. any lower is a right angle or acute angle, and higher is a straight line or a reflex angle.
What happens when the angle of refraction is 90 degrees or greater?
When the angle of refraction is 90 degrees or greater, the refracted ray will actually travel along the boundary between the two materials. This phenomenon is known as total internal reflection, which occurs when light travels from a medium with a higher refractive index to one with a lower refractive index at a steep angle.
When a beam of light passes at an oblique angle into a material of lower optical densitythe angle of incidence is?
greater than the angle of refraction
What shapes are obtuse angle?
obtuse is180 degrees so it would be larger than a 90 degree or lower angle
What is the measure of and obtuse angle and acute angle?
An obtuse angle is anything that measures between 91-179 degrees. (because 90 degrees is a right angle and 180 is a straight angle) An acute angle is anything that is lower than 90 degrees.** TIP: I remember acute angles because it has the word cute in it and I think "Oh it's so cute."
