What is an T square?
A T square is a drawing instrument used by engineers and draftsmen to come up with engineering design drawings. Consists of two arms at right angles to each other (usually made of wood). One arm is shorter than the other and the shorter arm slides against the edge of a drawing board and the longer arm is used to draw precise parallel and perpendicular lines and other equally accurate lines using set squares and protractors additionally.
What are examples of things you can measure in feet?
A foot is a unit of distance about the length from your wrist to your elbow. Anything you can measure can be expressed in feet. If it is smaller than your arm or longer than a portion of a mile then I would probably choose a different measurement.
Is it possible to draw a reflex angle so the other angle formed by the arm is acute?
No, it is not possible to draw a reflex angle where the other angle formed by the arm is acute. A reflex angle measures between 180 and 360 degrees, while an acute angle measures less than 90 degrees. Therefore, the other angle formed by the arm in a reflex angle scenario would have to be obtuse, measuring between 90 and 180 degrees.
Which lever would have more mechanical advantages than one with a resistance arm of 3 inches and an effort arm of 6 inches?
a lever with an effort arm of 2 inches
Is it possible to draw a reflex angle so the other angle formed by the arm is obtuse?
yes. if the reflex angle is 260 degrees, the other is 100 which is obtuse
