It could be four times per day: 9 AM, 9 PM, 3 AM, and 3 PM. Note: The question as stated is false and would likely cause controversy if it was on an important exam. The question should be "If the minute hand is pointing to the twelve and the hour hand is perpendicular to the minute hand, what times could it be?"
yes they do. they have a perpendicular line. * * * * * No, a pentagon, as in a regular polygon does not have perpendicular lines. An irregular pentagon could, and you can always add perpendicular lines to any shape.
Negative reciprocal slopes always represent perpendicular lines.
If the field lines were not perpendicular to the surface, then they could be decomposed into components perpendicular and parallel to the surface. But if there is an E-field along the surface, the surface is no longer an equipotential.
False. It could be a rhombus.
The only requirement for a trapezoid is that one pair of opposite sides be parallel. There could be trapezoids with a pair of perpendicular lines.
It could be but does not have to be... (Perpendicular to what?)
"could you call me in a minute" is the more acceptable term.
yes they do. they have a perpendicular line. * * * * * No, a pentagon, as in a regular polygon does not have perpendicular lines. An irregular pentagon could, and you can always add perpendicular lines to any shape.
A regular pentagon has zero perpendicular sides. If it is irregular, it could have as many as 2 or 4 perpendicular sides.
Negative reciprocal slopes always represent perpendicular lines.
yes a triangular prism has got 1 perpendicular face, at the base.
Nothing in particular - he could have been talking about you and pointed you out to whomever it was to show you to them, he could be just pointing to bother you, he could have actually been pointing in your direction and it actually had nothing to do with you. I wouldn't read too much into it.
You could baby sit
Yes in equilateral triangle.
Not necessarily. It could be a pentagonal based pyramid.
Would you believe twelve?
