What is a 145 degree angle called?
acute angle-an angle between 0 and 90 degrees. obtuse angle-an angle between 90 and 180 degrees.
How much is 145 angle?
145 degrees = 2.531 radians Formula: multiply the value in degrees by the conversion factor ‘0.017453292519931’.
What type of angle is a 140 angle?
What is the complement of 145 degrees?
Let the complement of 145 degree be x . x = 90 – 145. your answer is 235 degrees.
Can an angle be both complementary and vertical?
1 Answer. Complementary angles are those that sum up to 90o . Vertical angles have equal measures. Therefore, if vertical angles measure 45o each, they are complementary.
Is this statement true or false complementary angles have a sum of 90 degrees?
You can also tell that they are supplementary because when you add their angle measures the sum is equal to 180 degrees. Complementary angles are a pair of angles whose sum is 90∘. If you add up the two angle measures, the sum is equal to 90 degrees.
Are same alternate interior angles congruent?
Alternate interior angles are formed by a transversal intersecting two parallel lines . They are located between the two parallel lines but on opposite sides of the transversal, creating two pairs (four total angles) of alternate interior angles. Alternate interior angles are congruent, meaning they have equal measure.
Can complementary angles be congruent?
Complements of congruent angles are congruent. If two angles are complementary to two other congruent angles, then they’re congruent.
How do you know if an angle is supplementary or congruent?
Two angles are supplementary if the sum of their measures is 180. An isosceles triangle has at least two congruent sides. If two collinear segments adjacent to a common segment are congruent, then the overlapping segments formed are congruent.
Do similar triangles have congruent angles?
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion . In other words, similar triangles are the same shape, but not necessarily the same size. The triangles are congruent if, in addition to this, their corresponding sides are of equal length.
