What kind of angle is 120 degrees?
It is an obtuse angle
What is the measure of the angle formed by two tangents drawn to a circle from an external point if they intersect a major arc whose measure is 230?
-- The major arc = 230 degrees-- The minor arc ... the arc between the tangents ... is (360 - 230) = 130 degrees.-- The line from the vertex of the angle to the center of the circle bisects the arc,so the angle between that line and the radius to each tangent is 65 degrees.-- The radius to each tangent is perpendicular to the tangent. So the radius, the tangent,and the line from the vertex to the center of the circle is a right triangle.-- In the right triangle, there's 90 degrees where the radius meets the tangent, and65 degrees at the center of the circle. That leaves 25 degrees for the angle at thevertex.-- With another 25 degrees for the right triangle formed by the other tangent,the total angle formed by the two tangents is 50 degrees.
How do you describe an acute angle?
It is an angle more than 0 degrees but less than 90 degrees. An acute angle is any angle of between 0 and 90 degrees. A right angle is an angle that measures exactly 90 degrees. An obtuse angle is an angle that measure between 90 and 180 degrees. To remember the difference between an acute angle and an obtuse angle, think of "a cute" (acute) puppy and an large obese (obtuse) bulldog. Kind of cheesy but the words do sound alike and might help you remember
What kind of angle does a rhombus have?
Two acute angles and two obtuse angles. If you do not know what these angles are, I will show you. An acute angle is an angle that has less than 90 degrees on your protractor (Shaped like a semi-circle. Found in a mathematical set). An obtuse angle has more than ninety degrees. An angle with ninety degrees is a right angle.
If an angle measures 270 degrees what kind of angle is it?
its an obtuse angle ou retard... so so so so so so so
