An angle of 180 degrees has no name, but its subtending lines would form one straight line.
When two perpendicular lines cross you get four equal angles of 90 degrees.
There are three lines, three angles, and three sides or a triangle. Each angle of the equilateral triangle is exactly 60 degrees, because each angle is equal.
Draw two lines of equal length meeting at a vertex. Make sure that the angle between the lines is not 90 degrees. At the far end of each of these lines, draw a line, again equal in length, at an angle that is supplementary to the first angle.[Two angles are supplementary if their sum is 180 degrees.]
When 2 straight lines intersect vertical opposite angles are equal and the 4 angles created add up to 360 degrees
An angle of 180 degrees has no name, but its subtending lines would form one straight line.
Longitudinal lines themselves are imaginary constructs, having no real width, and therefore, no angle to measure. The angle between longitudinal lines on a globe depend on how many longitudinal lines are used to encircle the globe. Assuming that all longitudinal lines are equidistant, the angle can be found by dividing 360 degrees by the number of longitudinal lines. Typically, a globe will be given 36 lines of longitude, so the angle between longitudinal lines is equal to 360 degrees divided by 36 lines, or 10 degrees.
Construct a 90 degree angle isosceles triangle which will have equal sides and then divide the base into 9 equal parts joining the parts by lines to the apex of the trangle. Each line represents 10 degrees and 8 lines will equal to 80 degrees.
When two perpendicular lines cross you get four equal angles of 90 degrees.
"right angle" is two lines that intersect at 90 degrees "acute angle" is when 2 lines meet at less than 90 degrees "obtuse angle" is when lines meet at an angle more than 90 degrees , a straight angle is when 2 lines meet at exactly 180 degrees.
90 degrees angle
There are three lines, three angles, and three sides or a triangle. Each angle of the equilateral triangle is exactly 60 degrees, because each angle is equal.
Draw two lines of equal length meeting at a vertex. Make sure that the angle between the lines is not 90 degrees. At the far end of each of these lines, draw a line, again equal in length, at an angle that is supplementary to the first angle.[Two angles are supplementary if their sum is 180 degrees.]
true or false ? perpendicular lines intersect at an angle of 45
A right angle which is ninety degrees or 360 degrees which is a revolution.
When 2 straight lines intersect vertical opposite angles are equal and the 4 angles created add up to 360 degrees
If the angle between the lines is 90 degrees the lines are perpendicular.
