Parallel
Whether or not the opposing angles of a trapezoid (UK trapezium) are equal depends on the axis of symmetry. A trapezoid (trapezium) can be defined as a quadrilateral with one pair of opposite sides parallel. It is not a parallelogram because only one pair of sides is parallel. It is called a regular trapezoid if the sides that aren't parallel are equal in length and both angles coming from a parallel side are equal
Wikipedia defines a trapezium (trapezoid) as a quadrilateral with one pair of parallel sides. However, it also acknowledges that there is disagreement as to whether or not that means exactly one pair or at least one pair. Under the first definition a trapezium could not be a square whereas under the second, it would. Sorry not to give you an unambiguous answer but ...
A triangle. The effect of turning will depend on whether the plane containing the triangle is rotated - that is, the triangle is rotated around an axis perpendicular to its plane. In that case, it will appear upside down. Alternatively, it can be rotated about an axis in the plane of the triangle. In this case it will appear flipped.
Since parallelograms are four sided figures where each pair of opposing sides are parallel, and squares are four sided figures with all sides and angels congruent, then anything which is a square must also be a parallelogram. The statement is therefore false.
It depends on whether you consider rectangles and other parallelograms to be forms of trapezoids.If a rectangle can be considered a special case of a trapezoid (UK trapezium), and an isosceles trapezoid is modified so that any of its angles is 90 degrees, then it is a rectangle. In other words, it becomes a trapezoid with all right angles.However, you can also consider that trapezoids and parallelograms are two different kinds of quadrilaterals: trapezoids having one set of parallel sides and parallelograms having two sets. Then a trapezoid can never be a rectangle, or it would just be called a rectangle.
Points cannot be parallel or perpendicular. So they never are.
The straight line equation is y = mx + b. If they do not cross and have the same slope they are parallel; if they cross and the slope (m) of one of them is the negative inverse slope of the other (-1/m) they are perpendicular. Otherwise they are neither
Slope of line 1 is 1/3 and slope of line 2 is 1/3 which means the lines are parallel
Base on the slope of two linear equations (form: y = mx+b, where slope is m): - If slopes are equal, the 2 graphs are parallel - If the product of two slopes equals to -1, the 2 graphs are perpendicular. If none of the above, then the 2 graphs are neither parallel nor perpendicular.

There should be a lever somewhere on the duct near the furnace. If it is open, the lever will be parallel to the duct. If the damper is closed, it will be perpendicular to the duct.
By definition, A perpendicular line is a line that makes 90 degrees(right angle) with another line. It doesn't state whether it passes through or not. So, the answer to the question, is it depends. If there is a figure, follow it.

The answer will depend on whether you mean parallel edges or parallel faces.
No, a charged particle will experience a force when moving through a magnetic field as long as it has a non-zero velocity component perpendicular to the field. This force is known as the magnetic Lorentz force.
They're parallel if their slopes are equal.
To determine if a gas line is turned on or off, locate the gas meter and check the position of the valve. If the valve is parallel to the gas pipe, it is open (on). If it is perpendicular, it is closed (off). Be cautious and consider seeking professional help if unsure.
