If there were not that difference of 3o, the angles would be 60 and 30. Because of the difference the angles must be 61o and 29o.
You can find the area when you look at the angles and measure it to see if they are all the same size.
When a polygon is regular, each exterior angle is equal to the other exterior angles. Since the sum of all the exterior angles is 360 degrees, if you divide 360 by the measure of one exterior angle, you will get the number of sides. If you instead have the measure of an interior angle, simply calculate (180 - interior angle measure) to find the measure of the exterior angle, and use the above paragraph.
To find the angles of a parallelogram, you have to know at least one angle (although it could be an interior or an exterior angle). There are several facts about all parallelograms:the sum of the interior angles is 360˚ (true for all quadrilaterals)opposite angles are congruent (angles that are diagonal in parallelograms have the same measure)consecutive angles are supplementary (angles that are connected by a single side add up to 180˚)If you know any of the interior angles, you can use a combination of the above rules to find the rest. If all you know is an exterior angle, then use the fact that an interior angle and its exterior angle are supplementary (because they are a linear pair--they make a line) to find the measure of the interior angle; then use the rules given above.

It often gives us a way to find the measure of other angles.
Find the measure of this angles m1 equals 123 m8 equals?
You need to measure them.
4140Improved Answer:-Exterior angles = 360 degreesInterior angles = 4140 degrees
The other two angles each measure 90 degrees
You can use various properties of angles to find the measure of the second angle. For example, if you can see that the two angles form a right angle, then you know they add up to 90°, so you can subtract the known measure from 90° to find the measure of the other.
Yes, congruent angles are angles that have the same measure.
the larger angle is 60 and the smaller angle is 30.complimentary angles are 2 angles forming 90 degrees.
A protractor is nused to measure angles in degrees.
simple , measure them then times by 6
measure with an protacter
