What else can I help you with?
Two angles that can be trisected with a straightedge and compass are a 90 degrees angle and what other degree of angle?
45 and 90 degree angles
Are all straight angles straight lines?
Think about this: A straight angle makes 180 degrees, right? Straight lines, when measured by a compass, are also 180 degrees. So, yes, all straight angles are straight lines.
How do you construct angles without using protractor?
you might not be able to construct all the angles, but using a compass you can construct some angles by constructing angular bisectors. eg:construct angular bisector of straight line i.e; 180 degrees it gives 90 degrees
How do you construct an angle of 135 degrees using compass?
In addition to a compass, you WILL need a straight edge.Draw a long straight line.Using the compass and straight edge, and standard procedures, draw a perpendicular bisector of the line.Then, using other standard geometrical construction procedures, bisect one of the right angles to produce a 45 degree angle.The remaining right angle and the 45 degree angle next to it will be 135 degrees - as required.
Two adjacent angles that form a straight line?
they are called supplementary angles. a straight line has 180 degrees each side and two adjacent angles forming 180 degrees are called supplementary angles.
Two angles that can be trisected with a straight edge and compass are 60 in 45 angle's?
An angle of 60 degrees can be trisected using a straightedge and compass, resulting in three angles of 20 degrees each. However, a 45-degree angle cannot be trisected using these tools, as it does not yield a constructible angle with rational coordinates. This limitation arises from the fact that the trisection of a 45-degree angle leads to angles that are not constructible with straightedge and compass. Thus, while 60 degrees is trisectable, 45 degrees is not.
Two angles that can be trisected with a straightedge and compass are a 90 degrees angle and what other degree of angle?
45 and 90 degree angles
What are the two angle measures that can be trisected with a straightedge and compass?
The two angle measures that can be trisected using a straightedge and compass are 0 degrees and 180 degrees. Any angle that is a multiple of these measures can also be trisected. However, it is important to note that most arbitrary angles cannot be trisected using just these tools due to the limitations established by the impossibility of certain constructions in classical geometry.
Which angle can be trisected by using a compass and straightedge?
Only certain angles can be trisected using a compass and straightedge, specifically those that are multiples of 90 degrees. A notable example is the angle of 0 degrees or 90 degrees itself, which can be easily divided into three equal parts. However, in general, most angles cannot be trisected using these classical tools due to the limitations imposed by the field of constructible numbers, as proven by the impossibility of trisecting a general angle.

What is a straight angles degrees?
If you mean a straight line, then 180 degrees.
What is least count of prismatic compass?
The least count of a prismatic compass is typically 0.5 degrees. This means that the compass can measure angles accurately to within 0.5 degrees.
What does an angle of 180 degrees called?
It is a straight line because angles on a straight line add up to 180 degrees but angles greater than 180 degrees are reflex angles

An angle measure 180 is called?
Angles that are 180 degrees (θ = 180°) are known as straight angles. • Angles between 180 and 360 degrees (180°< θ < 360°) are called reflex angles.
How many degrees in 2 straight angles?
180 degrees
