What is the complementary angle of 90?
Complementary angles are those that add up to 90. Therefore, the complementary angle of 90 is 0.
How do you use a protractor to measure angles?
put the protractor on the vertex and look up at the degree's and look belowacute angle =has a measure between 0 degree's and 90 degree'sright angle =has a measure of 90 degree'sobtuse angle = has a measure between 90 degree's and 180 degree'sstraight angle = has a measure of 180 degree'sthat's how you use a protractor to measure angles.
What is the complement of 90 degree angle?
the answer is 0 because 90-90=0
What kind of angle is represented by 23 degrees?
An ACUTE Anglke. NB Angles less than 90 degrees are ACUTE angles. Angles between 90 degrees and 180 degrees are OBTUSE angles. Angles greater than 180 degrees are REFLEX angles.
Angles that measure less than a right angle?
anythin between 0 degrees and 90 degrees (called acute angles)
What do you know about the tangent of complementary angles?
OK, from what I learned is Complementary angles have 2 angles and have a 90° angle. And 0 and 90° are complementary angles. Um, that's all I know.
What is the complementary angle of 90?
Complementary angles are those that add up to 90. Therefore, the complementary angle of 90 is 0.
Can two obtuse angles be complementary angles?
sometimes... * * * * * No, never. Two angles are complementary angles if their measures sum to 90 degrees. An obtuse angle has a measure in the range (0, 90) degrees so two of them cannot sum to 90 degrees.
What part of the Earth's surface is represented at 0 45 and 90 degree angles?
0=45 degrees?
What are complementary angles always?
Complementary angles are angles that always add to 90° (ninety degrees). They are usually adjacent to each other, however in theory do not have to be. An example is: Angle "a" is 38°, and is situated next to, or adjacent to Angle "b" which is 52°. In this case, both angles (38 and 52) sum to ninety degrees, which means Angle a is complementary with, or to, Angle b. Another example is: Angle "a" is 56°, and is situated next to, or adjacent to Angle "b" which is 43°. In this case, both angles (56 and 43) do not sum to ninety degrees, which means Angle a is not complementary with, or to, Angle b. Complementary angles are studied in conjunction with supplementary angles (angles which sum to 180°) and angles at a point (angles which sum to 360°). Note: There does not have to be only two angles (however this is the minimum requirement, because a ninety degree angle can't have a complement of 0°). There can be three, five, ten, twenty, or whatever number of angles you wish (remember, you are not limited to there being ninety one degree angles because angles can have decimal points too, i.e. 56.32°). Hope this helped.
What are the 5 classification of the angles?
Angles can be complementary, supplementary, alternate, corresponding, perpendicular ..... etc but there are only 4 main angles which are as follows:- Acute angle is greater than 0 but less than 90 degree Right angle is 90 degrees Obtuse angle is greater than 90 but less than 180 degrees Reflex angle is greater than 180 but less than 360 degrees which is a complete revolution
What are the 4 degree numbers on a rhombus?
Suppose on of the angles is A degrees where 0 < A < 90. Then the opposite angle is also A degrees and the two adjacent angles are (180 - A) degrees.
How many right angles on all the faces of a Octagonal Prism?
According to my calculations, I am a complete nerd, and the answer to your question is 0, there are no 90 degree angles in an octagonal prism.
Can an angle be complementary if its 90 degrees?
Yes, it would be complementary to an angle measuring 0 degrees.

This describe and angle having a measure greater then 90 and less then 180?
It's an obtuse angle.Classifcations of angles:Acute angle: Angles that are greater than 0 degrees and less than 90 degrees.Right angle(perpendicular angle): Angles that are 90 degrees.Obtuse angle: Angles that are between 90 degree and 180 degrees.Straight angle: Angles that are 180 degrees.
What are the kinds of triangle acording to their angles?
equilateral triangle has all angles of 60 degrees isosceles triangle has only two equal angles scalene triangle have no equal angles acute triangle has all angles less than 90 degrees right angle triangle has one angle of 90 degrees obtuse triangle has one angle greater than 90 degrees right isosceles triangle has 90, 45, 45 degree angles assuming two angles are the same: acute isosceles triangle can range from <90,>45,>45 down to >0,<90,<90 obtuse isosceles triangle can range from >90,<45,<45 up to <180,>0,>0
