Parallel lines are lines that never intersect, and they form the same angle when they cross another line. Perpendicular lines intersect at a degree angle, forming a square corner.

Which term describes lines that meet at right angles

Some examples are: the sides of a set square, the arms of a clock, the corners of the blackboard, window and the Red Cross symbol. The point of intersection of perpendicular lines is called the foot of the perpendicular. Step 1: Let m be the given line and A the given point on it. Step 2: Place the protractor on the line m such that its base line coincides with m , and its centre falls on A. Step 3: Mark a point B against the 90 degree mark on the protractor. Step 1 : Place a compass tip on the given point A. Take an appropriate radius and draw an arc on either side of the given point. Step 2: Stretch the compass wider. Place the compass tip on the new points and make a small arc above the given line. The two new arcs will intersect. Step 3 : Use the ruler to join the given point A and the point B where the arcs intersect. Give your children opportunities to observe perpendicular lines in objects or places around them, such as a tall tree on the ground, an electric pole on the pavement, railway intersection, corner of two adjacent walls, and high buildings. Example 1: State whether a given set of lines are perpendicular or parallel. Example 2: Write a relation between the line segments indicated by the arrow in each shape.

All other images do not have lines intersecting at right angles.

Parallel and perpendicular lines are two important concepts in geometry. Parallel lines are the lines that never intersect each other. Thus, two parallel lines always maintain a constant distance between them. Perpendicular lines are the two lines that intersect each other at a right angle. We come across examples of parallel lines and perpendicular lines in daily life.

Wiki User. The perpendicular bisector of the line XY will meet it at its midpoint at right angles. That refers to lines that meet at right angles - angles of 90 degrees. The right angles in a pentagonal prism happen where the long faces meet the pentagonal end-caps. Therefore, there are 10 right angles in the form. That depends on the equation that it is perpendicular too which has not been given but both equations will meet each other at right angles. A three sided pyramid one of the vertexes of a cube passing through a plane would meet the criteria. On a plane manys polygon can have 3 right angles with the other angles totaling 90o. On the surface of the Earth a set of lines can be established that are 90o to the equator that meet at the north pole at 90o as well.

Which term describes lines that meet at right angles

Imagine two separate and distinct lines on a plane. There are two possibilities for these lines: they will either intersect at one point, or they will never intersect. When two lines intersect, four angles are formed. Understanding how these angles relate to each other can help you figure out how to measure them, even if you only have information about the size of one angle. Parallel lines are two or more lines that never intersect.

Parallel lines never intersect. Log in. So, for example, line ST is perpendicular to line CD. Posted 12 years ago. If its truly intersecting lines, they have to form right angles. The perpendicular bisector of the line XY will meet it at its midpoint at right angles. Step 3: Mark a point B against the 90 degree mark on the protractor. Related questions. Perpendicular lines meet at right angles. Example 2: Write a relation between the line segments indicated by the arrow in each shape. All Rights Reserved. We know that the slopes of two parallel lines are equal, i.

In geometry , when two rays meet each other at a common point, they form an angle.

Do parallel lines only exist in concept? Correct answer is: Laptop Laptop has edges intersecting at right angles. It's a good thing that wasn't because it would look very strange. Examples: Horizontal line and vertical line in the letter T, Hands of a clock when the analog clock reads Couldn't one write that CD is perpendicular to ST and still be correct? Do machines also have a very slight error when creating parallel lines? Best Answer. And one way to verify, because you can sometimes-- it looks like two lines won't intersect, but you can't just always assume based on how it looks. Adjacent sides of a rectangle. Posted 6 years ago. Describes lines that meet at right angles as in a transverse wave? A basic geography questions - Do all of the parallels and the meridians cross each other at right angles on both the globe and Mercator?
