<p>To prove that the sum of the angles in the four segments exterior to a cyclic quadrilateral is equal to 6 right angles, we can follow these steps:</p><p>1. <strong>Draw the Cyclic Quadrilateral</strong>: - Let PQRS be a cyclic quadrilateral. This
interior angle- the angle inside two adjacent sides of a polygon internal angle angle- the space between two lines or planes that intersect; the inclination of one line to another; measured in degrees or radians reentering angle,reentrant angle- an interior angle of a polygon that is greater ...
With the influence of strong mining disturbance, rock burst is easily induced by dynamic and static combined load in the advanced segment of gob-side entry. To achieve stability control similar to that in the roadway, the key control strategy is to reinforce surrounding rock and unload both ...

isosceles trapezoid are equal. The area of a trapezoid (whether or not isosceles) is half of the lengths of the parallel sides multiplied by the height, which is the perpendicular distance between the sides. The area of a trapezoid is also equal to the product of the mid-segment and the ...
The difference between my two largest angle measures is a two digit number x. One of the digits of x is twice the other digit. Angle Measure Line segmentABis intersected by segmentDC, with D onAB, between A and B. In triangle ADC, m∠ADC = 30º + x and m∠DAC = 50º ...

In a polygon, a diagonal is a segment that has as endpoints two nonadjacent vertices. In a polygon with {eq}n {/eq} sides, each vertex is the endpoint of {eq}n - 3 {/eq} diagonals. When we fix a vertex and draw one diagonal, the original polygon is divided into two; when we...

A chord is a segment that has its endpoints on a circle. The diameter is the longest chord of a circle and it passes through the center of a circle. A line is called a straight angle and it forms a 180 degree angle. A central angle is an angle with its vertex at the center of ...
