Is up and down perpendicular?
NO!!! Perpendicular means a line is at right-angles( 90 degrees) to anotyher line. 'Up & 'Down' are the directions of movement in a vertical maNNER.
How can you determine if two lines are perpendicular?
If the angle formed between the intersecting lines are 90o then the two lines are perpendicular. In 2D coordinate geometry, a perpendicular line has a slope equal to the negative reciprocal of the original line.
What letter of the alphabet has a perpendicular line?
Many letters of the English alphabet have perpendicular lines. Perpendicular lines are like two lines making one corner of a square. So any letter that has two lines joined like the corner of a square has perpendicular lines.These letters have right angles: E, F, f, H, I, L T, t, and sometimes X, x.Keep in mind that the angles of the lines making the letters is effected by the font and whether or not the letter is italicized. For example, E is made of three perpendicular lines, but this 'E' has no perpendicular lines.
Is a square a perpendicular or not?
The segments of a square are perpendicular. Take the letter " T " for example. Where the bottom line connects the the top line forms a 90 degree angle, which makes them two lines perpendicular.
How do you find a slope of a line perpendicular?
If two nonvertical lines are perpendicular, then the product of their slope is -1.An equivalent way of stating this relationship is to say that one line is perpendicular to another line if its slope is the negative reciprocal of the slope of the other. For example, if a line has slope 3, any line having slope - 1/3 is perpendicular to it. Similarly, if a line has slope - 4/5, any line having the slope 5/4 is perpendicular to it.
