To prove that opposite segments (angles) are equal to 180 degrees, you can use the concept of supplementary angles. If two angles are formed by intersecting lines, the angles opposite each other (vertical angles) are equal, while the adjacent angles formed by the intersection are supplementary. Thus, if you take one angle and its adjacent angle, their sum is 180 degrees. Therefore, the opposite angles must also relate in such a way that they collectively sum to 180 degrees, reinforcing the idea that opposite segments are equal to 180 degrees.
What else can I help you with?
Do the opposite angles of a parallelogram equal 180 degree?
No, not necessarily. Think of a rhombus that is not a square. Its opposite angles are equal - either both acute (sum < 180) or both obtuse (sum >180).
Are the opposite angles in an inscribed quadrilateral equal 180?

Do opposite angles in a parallelogram add up to 180?
No. Opposite angles are equal. Adjacent angles are supplementary.
What are the properties of a parralelogram?
A parallelogram is a quadrilateral with opposite sides that are both parallel and equal in length. Its opposite angles are also equal, and the consecutive angles are supplementary, meaning they add up to 180 degrees. Additionally, the diagonals of a parallelogram bisect each other, dividing each diagonal into two equal segments. These properties apply to all types of parallelograms, including rectangles, rhombuses, and squares.
What angles are exactly 180 degrees?
An angle that is exactly 180 degrees is known as a straight angle. It represents a straight line, dividing the plane into two equal halves. This angle occurs when the two rays or line segments forming the angle point in exactly opposite directions. In geometric terms, any angle that measures 180 degrees is considered straight, regardless of the context in which it is used.

If two sides in a triangle are congruent then their opposite angles are?
Their opposite angle are equal and all 3 angles will add up to 180 degrees
What is the sum of the angles in a four sided shape?
The sum of the angles of a four sided shape is equal to 360 degrees. One way to prove this is to draw a diagonal line connecting two opposite vertices, resulting in two triangles. Since the sum of the angles of a triangle equal 180 degrees, and there are two resulting triangles, then the sum of the angles of two triangles (180 + 180) will equal 360 degrees.

What is true about corresponding line segments of an object that has been rotated 180 degrees about the origin?
The line segments will have been rotated by 180 degrees.
How do you prove that in an isosceles trapezoid opposites angle are supplementary?
Because its base angles are equal and the 4 interior angles of any quadrilateral add up to 360 degrees so in this case opposite angles must add up to 180 degrees
What angles does a parallogram have?
A parallelogram is a four-sided figure with opposite sides of equal length and angles not equal to 90 degrees (otherwise it would be a rectangle). Diagonally opposite angles will be equal, and adjacent angles will add up to 180 degrees.
What is a shape that has four equal sides and opposite angles equal?
A shape that has four equal sides and opposite angles equal is a rhombus. In a rhombus, all sides are of equal length, and while opposite angles are equal, adjacent angles are supplementary (adding up to 180 degrees). A square is a special type of rhombus where all angles are also right angles.
Are the opposite sides of a parallelogram supplementary?
Yes, the opposite sides of a parallelogram are equal in length, but they are not supplementary. Supplementary angles refer to two angles whose measures add up to 180 degrees. In a parallelogram, consecutive angles are supplementary, meaning each pair of adjacent angles sums to 180 degrees, while opposite angles are equal but not supplementary.
