It is an intersection.
They are perpendicular lines that meet at right angles which is 90 degrees.
A chord is a straight line joining any 2 points on the circumference of a circle
the bearing of something is the angle. for example there are 180 degrees on a straight line so the bearing of a straight line is 180 degrees. To work out the bearing of something though you need a protracter
Angle is a space between two lines or surfaces that meet at one point, which you measure in degrees.
A radian is part of the circumference of a circle and its length is the same size as the circle's radius and it is about 57.3 degrees.
right angles are perpendicular lines that intercept each other at right angles which is 90 degrees
it means maths
ruler
'Acute' in maths refers to an angle of less than 90 degrees.
Parallel in maths means opposite. Two parallel lines can never touch. I you are not sure if two lines are parallel then imagine that these lines go on for ever, will they eventually cross?
Lines that are neither parallel nor perpendicular.
you have to be good at all the sciences and maths
