What is the equation for parallel and perpendicular lines? Parallel lines, which are in the same plane but will never intersect, have the same slope. Perpendicular lines, which intersect at 90 degree right angles, have slopes that are negative reciprocals of one another.What...
We now know that two lines are perpendicular if they form an angle of 90owith each other. Now, if we have another line that joins these two lines, we form a triangle. What do we call such a type of triangle? Such an angle is called aright angled triangle. Also, if one of the a...

Slope Properties for Parallel and Perpendicular Lines Jill just learned about the relationship between slopes of parallel and perpendicular lines in math class, and Jill's teacher has asked her to prove these properties for homework. Jill is still confused by what she was taught and doesn't under...

(Chauliodus) looks like the thing nightmare fuel is made out of. But while dragonfish have what appear to be terrifying but manageable fangs, the viperfish got hit with a genetic misstep during some evolutionary split. Its sharp fangs are so long that if its jaw moves out of line, they...
Slope Criteria for Perpendicular Lines Directions: Supply reasons. Name___ Theorem: If two lines are perpendicular, their slopes are negative reciprocals. (The product of the slopes = -1.) Given: l 1 l 2 (let m1 = slope of l1; m2 = slope of l2) Prove: m1 = -1/m2 (m1 ...
Perpendicular When did perpendicular lose its verticality? I have always understood perpendicular as being “at right angles to the plane of the horizon” ie: at right angles and vertical. OED:- 1. perpendicular, adj. and n. ...Situated or directed at right angles to the plane of the hori...
