What an angle which measures 90 degrees?
A right angle. A square has 4 right angles.
Are reference angles and radians the same?
No. A radian is a measure of an angle, it is not, itself, an angle. Degrees and radians are measures of angles and the two measures are related by the following conversion: 180 degrees = pi radians
Interior and exterior angles of a 30 sided polygon?
The total of the interior angles equal 5040, and each angle measures 168 degrees The total of the exterior angles equal 360, and each angle measures 12 degrees
One angle of a parallelogram measures 10 degrees. What are the measures of the other three angles in the parallelogram?
If one angle is 10 degrees, its opposite angle is also 10 degrees. Since consecutive angles are supplementary, each pair of angles has to add up to 180 degrees so the other angles have to be 170 degrees. Therefore this parallelogram has two 10 degree angles and two 170 degree angles.
Two angles whose measures have a sum of 90 degrees are?
Complementary angles.
What are complmentary angles?
two angles that add up to 90 degrees, (half of a supplementary angle.)
What is the sum of the measures of the interior angles of a regular polygon if each angle measures 90 degrees?
If each angle measures 90 degrees the polygon is a square and so its angles sum to 360 degrees.
What are angles that together measure 180 degrees?
A straight angle is an angle that measures 180 degrees and is drawn as a straight line. A straight angle is composed of two right angles whose measures are 90 degrees each.
What are all the angles in a regular hexagon called?
Exterior angles are acute because each angle measures 60 degrees Interior angles are obtuse because each angle measures 120 degrees
What is the exterior and interior angles of a regular 20-gon?
Exterior angle measures 18 degrees Interior angle measures 162 degrees
If one angle of a parallelogram measures 40 degrees and another angel measures 140 degrees what are the measures of the other two angles?
The other two angles are also 40 degrees and 140 degrees.
What has an angle that measures 90-180 degrees?
270
What an angle which measures 90 degrees?
A right angle. A square has 4 right angles.
Are reference angles and radians the same?
No. A radian is a measure of an angle, it is not, itself, an angle. Degrees and radians are measures of angles and the two measures are related by the following conversion: 180 degrees = pi radians
In a right-angled triangle besides the right - angle one of the angles measures 30 degrees what does the other angle measures?
60 degrees. There are 180 degrees in a triangle.
What is one of the angles on a regular 20-gon?
Each exterior angle measures 18 degrees Each interior angle measures 162 degrees
What are two angles that have the same measures have the sum of 90?
Two angles that have the same measure and sum up to 90 degrees are complementary angles. For example, if one angle measures 45 degrees, the other angle will also measure 45 degrees, and their sum will be 90 degrees.
