They can be: acute, right angle, obtuse or reflex
Each angle has a measure of 120 degrees
If you mean exterior angle is twice its interior angle then an equilateral triangle will fit the given description because each interior angle is 60 degrees and each exterior angle is 120 degrees
Remote interior angles are the angles that are not adjacent to a given exterior angle but are inside the triangle. For each exterior angle of a triangle, there are two remote interior angles. The sum of these remote interior angles is equal to the measure of the exterior angle. Thus, if you have a specific exterior angle, you can identify the two corresponding remote interior angles.
A parallelogram is a figure with different lengths and widths(also called breadth) where opposite sides and opposite angles are equal. But the angles are not 900 each. In fact, no angle in a parallelogram is a right angle as presence of 1 right angle proves all the angles to be right angles. A parallelogram with 4 right angles is called as a ''rectangle''
The opposite angles are congruent and all add to 360 degrees
The sum of the measures of the angles in a figure having 9 sides is 20 degrees each angle.
The sum of the measures of the angles in a figure having 9 sides is 20 degrees each angle.
No, a rectangle is not a figure with no angles. A rectangle is a quadrilateral with four right angles. Each angle in a rectangle measures 90 degrees. If a figure has no angles, it would be a circle, which has no straight lines or angles.
Each angle has a measure of 120 degrees
A square or a rectangle would fit the given description
Opposite angles are angles across from each other in intersecting lines. For example, see the figure below:a-> X
If you mean exterior angle is twice its interior angle then an equilateral triangle will fit the given description because each interior angle is 60 degrees and each exterior angle is 120 degrees
A 12 sided figure is called a dodecagon. This type of polygon has 12 angles and each angle equals 150 degrees.
Without a visual or more information, I'm guessing that the picture is of angles 1 and 2 that are consecutive (share an angle side) and a separate picture of consecutive angles 3 and 4. With that said: 1) angle 2 congruent to angle 3................1) given 2) angle 1 is supplementary to angle 2....2) If angles are next to each other --> supps angle 3 is supplementary to angle 4 3) angle 1 congruent angle 4..............3) If supps to congruents angles ---> congruent

which pair of angles in the figure below are vertical angles ?
There are 4 internal angles in a square, and they are each 90o angles. There are also 4 external angles, though they are not addressed often. Each of the external angles is a 270o angle. A square is a four-sided figure which has four equal sides and four right-angles.
