What does angle mean?
Adjective angles? Maybe you meant adjacent angles. Adjacent angles are angles that share a side and a vortex (corner point).| /| /|/____________Pretty bad text drawin up there, but you see 2 angles sharing one side, and they also share a vortex.
How many right angles in a full rotation?
A full rotation = 360°; a right angle = 90° → there are 360° ÷ 90° = 4 right angles in a full turn.
Can four angles make up a full revolution angle?
Yes 4 angles can make of full revolution or a complete turn of 360 degrees.
What are a score or more facts about angles in geometry?
1 Angles are measured in degrees, minutes and seconds 2 Angles can be measured with a protractor 3 Angles can be found using trigonometry 4 Angles in a regular polygon are equal 5 Angles around a circle is a full rotation of 360 degrees 6 Angles around a point add up to 360 degrees 7 Angles in a polygon are: (n-2)*180 whereas 'n' is the number of its sides 8 Angles greater than 0 but less than 90 degrees are acute 9 Angle of 90 degrees is a right angle 10 Angles greater than 90 but less than 180 degrees are obtuse 11 Angles greater than 180 degrees are reflex 12 Angle of elevation is looking up at an object 13 Angle of depression is looking down at an object 14 Angles are formed when a transversal line cuts through parallel lines 15 Angles of 90 degrees are formed when perpendicular lines meet 16 Angles can be bisected with a compass and a straight edge 17 Angle of the tangent of a right angle triangle is: opposite/adjacent 18 Angle of the sine of a right angle triangle is: opposite/hypotenuse 19 Angle of the cosine of a right angle triangle is: adjacent/hypotenuse 20 Angle of rotation is used in a transformation on the Cartesian plane 21 Angles that meet at 180 degrees on a straight line are supplementary 22 Angles that form a right angle are complementary 23 Angles of 360 degrees once represented a year in ancient Babylonian 24 Angles of 518,400 degrees are passed by the minute hand of a clock in a day and 31,104,000 degrees by its second hand in 24 hours
Are all right angles similar?
All right angles measure 90 degrees, that is, one-quarter of a full circle. If the angle doesn't measure 90 degrees it isn't a right angle; all right angles are identical.
What are the all kinds of angle and an example?
Bsically...Obtuse- more than 90Right- 90Acute- less than 90Reflex-more than 180I thinkAn angle of 90° (π/2 radians, or one-quarter of the full circle) is called a right angle.Two lines that form a right angle are said to be perpendicular or orthogonal. Angles that are not right angles or a multiple of a right angle are called oblique angles.Angles smaller than a right angle (less than 90°) are called acute angles ("acute" meaning "sharp").Angles larger than a right angle and smaller than two right angles (between 90° and 180°) are called obtuse angles("obtuse" meaning "blunt").Angles equal to two right angles (180°) are called straight angles.Angles larger than two right angles but less than a full circle (between 180° and 360°) are called reflex angles.Angles that have the same measure (i.e. the same magnitude) are sometimes said to be congruent, though the diagrams that represent them need not be congruent, so others (including Euclid) prefer to say that they are equal in size, or just "equal".An angle of 90° (π/2 radians, or one-quarter of the full circle) is called a right angle.Two lines that form a right angle are said to be perpendicular or orthogonal.

These angles are equal in size.Angles that share a common vertex and edge but do not share any interior points are called adjacent angles.Two angles that sum to one right angle (90°) are called complementary angles. Two angles opposite each other, formed by two intersecting straight lines that form an "X"-like shape, are called vertical angles or opposite angles.

What is the measurement of the angles?
Angles greater than 0 but less than 90 degrees are acute angles. A 90 degree angle is a right angle. Angles greater than 90 but less than 180 degrees are obtuse angles. Angles greater than 180 but less than 360 degrees are reflex angles. A complete rotation of 360 degrees is a full turn.
How many degrees is in right angle triangle?
The right angle of a right-angle triangle, like all right angles, is 90 degrees or one quarter of 360 (a full circle). All the angles of any triangle will add up to 180 degrees.
What kind of angle is 150?
Angles less than 900 are called acute angles. 900 angles are called right angles. Angles that are greater than 900 and less than 1800 are called obtuse angles. 1800 angles are called straight angles. Anles greater than 1800 and less than 3600 are called reflex angles. 3600 angles are called full rotations. 1500 is therefore an obtuse angle.
What is a reflex measure of an angle?
A reflex angle is one that is greater than 180 degrees (a straight line) but less than 360 degrees (a full circle). When two lines meet (not cross), they will form two angles. Unless they meet head on, one of these will be less than 180 degrees and the other will be more; the two of them will add to 360 degrees. Conventionally the smaller of the two angles will be used as a measure of the angle. The reflex is the larger of the two.
What is a Angle unit of measure?
Angles are units of measure that define the relationships between two intersecting lines It's tough to demonstrate by text, but I'm goind to give it a try; _\ = an angle of about 60 degrees _/ = an angle of about 120 degrees _| = an angle of 90 degrees (also called a 'right' angle) _._ = an angle of about 180 degrees = is an angle of about 0 degrees
What are the angles of rhombus the lengths of the diagonal of rhombus are 14m and 34m?
As the diagonals of a rhombus bisect the angles through which they pass and intersect at right angles, we now have 7 and 17 as the sides of the triangles. We have:tan(x) = 7/17x = arctan(7/17)The half angle is about 22.38° and the full angle = 44.76°.The angle of the second set of paired angles is therefore 180 - 44.76 = 135.24o
