What are two angles whos sides are opposite rays?
they are vertical angles
Two angles whos sum is 180 degrees?
The term supplementary angle is used to refer to angles whose sum is 180 degrees. This is different from complementary angles which add up to 90 degrees.
Can a triangle have two angles?
No, a triangle cannot have two angles. Triangles always have three sides and three angles that add up to 180 degrees.
Can a polygon containing two right angles be a triangle?
No, because two right angles=180 degrees. A triangle has three sides and is 180 degrees, so two right angles would not form a triangle.
How many sides will a polygon have if the sum of its angles is twenty two right angles?
If the sum of its interior angles is 22*90 which is 1980 degrees then it will have 13 sides Consider the following rules that are applicable to all polygons:- (interior angles+360) divided by 180 = number of sides (number of sides -2) multiplied by 180 = sum of interior angles The above question is rather confusing because it implies that the interior angles of the polygon is the equivalent of twenty two right angles which is the same as 1980 degrees but working out how many sides the polygon has then the same rules apply. (1980+360)/180 = 13 sides (13 -2)*180 = 1980 degrees
Two angles whose measures add up to 180 are called what?
The angles are called supplementary if they add to 180 degrees. Where the two angles are adjacent, they form a "linear pair" such that their farthest sides lie on the same line.
How many sides and angles you can get from a square divided into two triangles?
Each triangle will have 3 sides and 3 interior angles that add up to 180 degrees
What figure has two conguruent sides and its angles measure up to 180 degrees?
An isosceles triangle.
What are the angles formed by two sides of a triangle?
Only one angle is formed by two sides of a triangle. It can be anything less than 180 degrees.
What are two adjacent angles called whose measures add up to 180 degrees?
They are called linear pair, because their farthest sides lie on the same line.Any two angles that add to 180 degrees are called supplementary angles.
Can a regular octagon have two acute angles?
All regular polygons have equal angles that can be determined with the following equation: 180(sides - 2) / sides 180(6) / 8 1080 / 8 135 degrees, so no, to answer your question a regular polygon cannot have two acute angles, they MUST all be obtuse.
What are the two properties of a triangle?
There are three sides and all internal angles add up to 180 degrees
