How does NASA use trigonometry?
Astronomers use trigonometry to calculate how far stars and planets are from Earth. Even though we know the distances between planets and stars, this mathematical technique is also used by NASA scientists today when they design and launch space shuttles and rockets.

two circles touch externally
If D lies on AB such that CD=6cm, then find AB. Your email address will not be published. To find : ∠ACB. The tangents intersecting between the circles are known as transverse common tangents, and the other two are referred to as the direct common tangents. Since AB = r 1 +r 2, the circles... | 677.169 | 1 |
Golden Rectangle
Construction of the golden rectangle
The golden rectangle, also known as the golden rectangle or golden ratio, is a special ratio between the lengths of the sides of a rectangle. A rectangle is said to be golden if the ratio of the length of the longer side to that of the shorter side is approximatel... | 677.169 | 1 |
Is any quadrilateral with a square is corner does it mean it's a square?
That is, a quadrilateral with no square corners is not a rectangle or a square. This is because by definition, a rectangle and a square have four square corners, so if a quadrilateral has no square corners, then it cannot be a rectangle or a squa... | 677.169 | 1 |
What is Euclidean geometry: Definition and 48 Discussions
Euclidean geometry is a mathematical system attributed to Alexandrian Greek mathematician Euclid, which he described in his textbook on geometry: the Elements. Euclid's method consists in assuming a small set of intuitively appealing axioms, and deducing many o... | 677.169 | 1 |
Determine whether the lines l1 and l2 are parallel skew or intersecting?
Sometimes it is hard to tell if two lines are parallel, skew or intersecting. The best way to find out is by determining the distance between them and then use a ruler to measure their angle. -First, measure the distance between lines l and l'. I... | 677.169 | 1 |
