What is the measure of the angles opposite to 122 degrees?
58 degrees
122 degrees plus our missing angle has to equal 180 degrees. If we take 180 degrees and subtract the 122 degrees, we come up with 58 degrees.
What are 120 degree angles called?
An obtuse angle is a type of angle whose degree measurement is more than 90° but less than 180°. Examples of obtuse angles are: 100°, 120°, 140°, 160°, 170°, etc.
How do you find opposite angles?
If angle A measures 100 degrees, then angle B, its opposite, will also measure 100 degrees. This means that the two angles combined equals 200 degrees. Remember that two sets of opposite angles measures 360 degrees (a full circle), so subtract 360 – 200 = 160.
What is a opposite angle?
Opposite Angles. Opposite angles are non-adjacent angles formed by two intersecting lines. Opposite angles are congruent (equal in measure).
What is the angle of a rhombus?
360 degrees
Angles of Rhombus Rhombus has four interior angles. The sum of interior angles of a rhombus add up to 360 degrees. The opposite angles of a rhombus are equal to each other. The adjacent angles are supplementary.
What type of angle is 134 degrees?
obtuse angle-an angle between 90 and 180 degrees.
What angle is a 180?
straight angle
A 180-degree angle is a straight angle and it is exactly half of a revolution. It is also called a half-circle angle. A straight angle is produced by a straight line. The two arms of the angle which are making 180-degree are just opposite to each other from the common vertex.
What is it called when opposite angles are equal?
Opposite angles are congruent (equal in measure).
What is the sum of adjacent angles of a rhombus?
All sides of the rhombus are equal. The opposite sides of a rhombus are parallel. Opposite angles of a rhombus are equal. In a rhombus, diagonals bisect each other at right angles. Diagonals bisect the angles of a rhombus. The sum of two adjacent angles is equal to 180 degrees. You will get a rectangle when you join the midpoint of the sides.
How many interior angles does a rhombus have?
Rhombus has four interior angles. The sum of interior angles of a rhombus add up to 360 degrees. The opposite angles of a rhombus are equal to each other. The adjacent angles are supplementary. In a rhombus, diagonals bisect each other at right angles.
What is the angle opposite of 122 degrees in a rhombus?
In a rhombus, opposite angles are congruent and adjacent angels are supplementary. Consequently, the angle opposite the 122 deg angle must be 122 deg. For geometry problems, I strongly recommend that you make a sketch.
What is the definition of rhombus in math?
Rhombus Definition. A rhombus is a special case of a parallelogram and it is a four-sided quadrilateral. In a rhombus, opposite sides are parallel and opposite angles are equal. Moreover, all the sides of a rhombus are equal in length and the diagonals bisect each other at right angles.
