The line that forms a 90 degree angle with any other line is called "perpendicular" or "orthogonal" to the other line.but u can call it right angled
a right angle
A line that is at right angles to a vertical line is said to be horizontal.
The only diagonal line in a right-angle triangle is the hypotenuse. So the answer is 1.
You use the right angle next to an acute angle perhaps and you see that when a angle is closer together it is an acute angle and if it is spread apart or farther apart from a right angle it is an obtuse angle. If the angle is a straight line and doesn't look bent like a right angle it is a straight angle.
Draw two line segments at a right angle, and add three more line segments to complete a closed figure.
right angle
It is a vertical line.
It is a perpendicular line that forms a right angle at the point of intersection.
It is a perpendicular bisector line
It is perpendicular line segment
It is a perpendicular bisector line
It is perpendicular line segment
hypotenuse
It is called a perpendicular bisector.
If the horizon is on a level line of sight, a vertical line directly above the observer forms an angle of 90 degrees. 55 degrees would be quite high, being above 45 degrees.
Perpendicular Bisector
An angle that forms a straight line has an angular measure of 180 degrees.
