Dois ângulos internos de um triângulo medem 45° e 57°. O terceiro ângulo interno mede:
-
88°
-
78°
-
68°
-
58°
Correct Answer
A. 78°Explanation
Seja x o terceiro ângulo interno. Como a soma dos três ângulos deve ser 180°:
x + 45° + 57° = 180°
x + 102° = 180°
x = 72°Rate this question:

Dois ângulos opostos pelo vértice sempre são:
-
Iguais
-
Complementares
-
Suplementares
-
Replementares
Correct Answer
A. IguaisExplanation
Two angles that are opposite each other at the vertex are always equal. This is because when two lines intersect, they form two pairs of opposite angles. These opposite angles are congruent or equal to each other. Therefore, in any given situation, if we have two angles that are opposite each other at the vertex, we can conclude that they are equal.Rate this question:

Na figura abaixo as retas a e b são paralelas. Determine o valor de x.
-
30°
-
60°
-
120°
-
45°
Correct Answer
A. 30°Explanation
2x e 60° são ângulos alternos internos, ou seja, são iguais. Assim:
2x = 60°
x = 30°Rate this question:

Qual é a diferença entre o suplemento e o complemento de qualquer ângulo?
-
45°
-
90°
-
180°
-
360°
Correct Answer
A. 90°Explanation
Seja x o ângulo. Assim, o complemento vale 90° - x e o suplemento vale 180° - x. A diferença entre eles é
suplemento - complemento = (180° - x) - (90° - x) = 180° - x - 90° + x = 90°Rate this question:

Na figura as retas são paralelas. Determine o valor de x.
-
40°
-
60°
-
80°
-
100°
Correct Answer
A. 60°Explanation
Quando temos paralelas ou os ângulos são iguais (quando são alternos internos ou alternos externos) ou os ângulos são suplementares. Nesse caso, como eles não são nem alternos internos nem alternos externos então eles são suplementares. Assim:
80° + 2x - 20° = 180°
2x = 120°
x = 60°Rate this question:

Dois ângulos alternos internos sempre são:
-
Complementares
-
Suplementares
-
Replementares
-
Iguais
Correct Answer
A. IguaisExplanation
Dois ângulos alternos internos sempre são iguais. Isso ocorre quando duas linhas paralelas são cortadas por uma transversal. Os ângulos alternos internos são os ângulos que estão em lados opostos da transversal, mas em lados internos das linhas paralelas. Devido às propriedades das linhas paralelas, esses ângulos têm a mesma medida. Portanto, a resposta correta é "iguais".Rate this question:

Um ângulo é igual ao seu complemento. Nesse caso, esse ângulo vale:
-
60°
-
30°
-
90°
-
45°
Correct Answer
A. 45°Explanation
Se o ângulo vale x seu complemento vale 90° - x. Como são iguais, temos:
x = 90° - x
2x = 90°
x = 45°Rate this question:

Qual ângulo é igual ao dobro do seu complemento?
-
60°
-
30°
-
180°
-
90°
Correct Answer
A. 60°Explanation
An angle is equal to twice its complement when the angle and its complement add up to 90 degrees. In this case, the complement of the angle is 30 degrees, and when we add 30 degrees to the angle, it equals 90 degrees. Therefore, the angle is equal to twice its complement, which is 60 degrees.Rate this question:

Dois ângulos colaterais internos sempre são:
-
Complementares
-
Suplementares
-
Replementares
-
Iguais
Correct Answer
A. SuplementaresExplanation
Two interior angles are considered collinear if they lie on the same side of the transversal line and the sum of their measures is equal to 180 degrees. Therefore, they are called supplementary angles.Rate this question:

Seja a um ângulo agudo. Assim, assinale as alternativas verdadeiras.
-
O complemento desse ângulo é 90° - a
-
O suplemento desse ângulo é 180° + a
-
O suplemento desse ângulo é 180° - a
-
O replemento desse ângulo é 360° - a
-
A diferença entre o suplemento de a e o complemento de a vale 180°
Correct Answer(s)
A. O complemento desse ângulo é 90° - a
A. O suplemento desse ângulo é 180° - a
A. O replemento desse ângulo é 360° - aExplanation
The correct answer is that the complement of the angle is 90° - a, the supplement of the angle is 180° - a, and the replement of the angle is 360° - a. These statements are all true because in an acute angle, the complement is the difference between 90° and the angle, the supplement is the difference between 180° and the angle, and the replement is the difference between 360° and the angle.Rate this question:
