To show that sin(90 degrees) is equal to 1, we can use the unit circle. At 90 degrees, the point on the unit circle has coordinates (0, 1), where the y-coordinate represents the sine value. Since the y-coordinate is 1 at 90 degrees, sin(90 degrees) is equal to 1. This can be visually represented on the unit circle diagramatically.

It is one whole turn.
360 degrees is one full turn- a complete circle.
One knot is equal to 1.1.5078 miles her hour. 1 mile per hour is equal to 0.868976 knots. A knot dervives not from mph but latitude; it takes 1 minute of time to travel one minute of latitude.
A trapezium and a square are both quadrilaterals, but the key difference is the number of parallel sides. A square has two sets of parallel sides and four right angles, while a trapezium has only one set of parallel sides. Parallel sides: A square has two pairs of parallel sides, while a trapezium has only one. Angles: A square has four right angles, while a trapezium can have any combination of angles as long as the interior angles add up to 360°. Side lengths: A square has four equal sides, while a trapezium can have sides of different lengths. Classification: A square is a regular quadrilateral because all its sides and angles are equal. A trapezium is not a parallelogram because only one pair of sides are parallel.
If the angles are the same and the sides are proportional by ratio then they are said to be similar triangles.
