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
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''
Total internal angles of an n-sided figure is (2n - 4)right angles Here we have (14 - 4)right angles = 10 x 90 degrees = 900 degrees, hence each angle would be 900/7 = 128.5714 degrees
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.
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.
Total internal angles of an n-sided figure is (2n - 4)right angles Here we have (14 - 4)right angles = 10 x 90 degrees = 900 degrees, hence each angle would be 900/7 = 128.5714 degrees
