How do you make a 60 degree angle?
With a protractor or construct an equilateral triangle which has 3 equal interior angles of 60 degrees
What kind of triangle has one 30 degree angle and one 60 degree angle?
A right triangle because all triangles equal 180 degrees. 180-60=120 120-30=90
Show how to construct a 120 degree angle?
draw a base and use this to draw an equilateral triangle each angle of an equilateral triangle adds up to 60 degrees. To have an angle of 120 degree use this angle and then draw another side of a triangle next to it to get a 120 degree angle.
How can you construct a 120 degree angle without using a protractor?
Construct an equilateral triangle which will have 3 equal interior angles of 60 degrees and 3 equal exterior angles of 120 degrees
What are some examples of right triangles that each have a 30 degree angle?
If a right angle triangle has an interior angle of 30 degrees then the other two angles must be 90 degrees and 60 degrees.
How do you construct a 50 degree angle using a pair of compass?
by 60 degree and 90 degree
How do you construct 105 degree angle with using compass?
with compass.........at 90+60degree angle,,,,,,,,, * * * * * and 90 + 60 = 105??? You need to draw a 90 degree ange and bisect it to give a 45 deg angle. Then add a 60 degree angle. 45 + 60 = 105.

Is 60 degree angle and 60 degree angle congruent?
yes
Are all 30-60-90 triangles isosceles?
No because 30-60-90 triangles are right angle triangles
How do you construct 22.5 degree with compass?
asuming you know how to construct a 60 degree angle, you would start by drawling a basic construction line an then make your angle bisecter with breaks the angle into 30 degree angles. then create another angle bisector for 30 degrees breaking it into 15 degree angles. then do the same with the 15 degree angle. your drawling sould have three angle bisectors for each angle. to get your answer of 22.5 degress angle, simply add the 15 degree angle you drew with the 7.5 angle you got from spliting the 15 degree angle in half its hard to explain without drawing it out..... hope this helps
How is a 30 degree angle related to a 60 degree anlge?
a 60 degree angle is twice the size of a 30 degree angle.
If any two sides and any angle are congruent in two triangles then the triangles must be congruent.?
No. The angles must be an included angle, between the sides to guarantee congruence. For an example. imagine a triangle with two equal sides and a 60 degree angle between them and another triangle with the same two equal sides and a 120 degree angle between them.
How do you draw an angle of 55 degree with compass and pencil?
you will have to construct a 135 degree angle first...but constructing a 90 degree with a 45 degree to give u the 135 degree angle and then using that as a reference, u will have to draw a 60 degree angle going counter clockwise from the 135 degree angle so that 135-60=55 degree...hahah I know it is confusing but if only i could show you...cz i mean visual is better than oral right !??! haha ^D^... hope i can help....
