What type of angle is 30 degrees acuterightobtuse or reflex?
A thirty degree angle is an acute angle.
What is the complement of a thirty-four degree angle?
Two complementary angles will have a sum of 90 degrees. Therefore, the complement of a 90 degree angle would be 90 - 34 = 56 degrees.
What type of triangle has an angle that measures 120 degrees and an angle that measures thirty degrees?
An isosceles triangle, because the angles of a triangle add up to 180 and you already know that one angle measures 120 degrees, the other is 30, and so the unknown angle must also be 30 degrees. Since two of the angles are the same, two of the sides are going to be the same, making it an isosceles triangle.
If an angle is obtuse then it has a measure of 120 degrees?
When an angle has a measure of 120 degrees, it is an obtuse angle. When an angle is an obtuse angle its measure is between 90 and 180 degrees. That is: 90 degrees < obtuse angle < 180 degrees.
What is a angle that is 142 degree angle?
An angle that measures 142 degrees is classified as an obtuse angle. In geometry, an obtuse angle is an angle that is greater than 90 degrees but less than 180 degrees. It falls between a right angle (90 degrees) and a straight angle (180 degrees).
