contingent angle
[kən'tɪndʒənt 'æŋɡəl]
nounpl: contingent angles
ângulo contingente
1. An angle formed between a tangent line to a curve and a chord drawn from the point of tangency; an angle between a tangent and a secant from the same point
The contingent angle at point P on the circle is formed by the tangent and the chord PQ.
O ângulo contingente no ponto P do círculo é formado pela tangente e pela corda PQ.
2. In geometry, specifically in circle theorems, the angle formed between a tangent to a circle and a chord drawn from the point of tangency
To solve this problem, we need to calculate the contingent angle using the inscribed angle theorem.
Para resolver este problema, precisamos calcular o ângulo contingente usando o teorema do ângulo inscrito.
This is a technical mathematical term used primarily in academic and educational contexts. It is not commonly used in everyday conversation in either Brazil or the USA. The term is part of standard geometry curriculum in secondary and higher education mathematics programs in both countries.
