there exist infinitely many geodesic triangles each of which has the same three vertices and satisfies the property that its three sides have the same and arbitrarily given length while its three angles are equal to any given three possibly different numbers from 0 to \\\(\\\pi \\\) . Thi...
INTRODUCTIONDuring a recent Grade 11 geometry lesson the class engaging with the theorem that angles subtended by a chord in the same segment of a circle are equal. As part of the discussion we touched on one of the corollaries of this theorem, namely that angles subtended by chords of ...
Since, angles in same segment at a circle are equal ∠6=∠B2 ∠1=∠B2 ∠2=∠C2 ∠3=∠A2 ∠4=∠C2 In∠DEF ∠E=∠3+∠4=∠A2+∠C2=∠A+∠C2 =180−∠B2 ∠E=90∘−∠B2 ∠D=∠B2+∠C2=∠B+∠C2 ∠D=90∘−∠A2 ∠F=∠5+∠6 =∠A2+∠B2=∠A+∠B2 ∠F=90∘...
Line SegmentWhen a line has two endpoints, it is known as a line segment. The length of a line segment can be measured and it is written as ¯¯¯¯¯¯¯¯ABAB¯AnglesWhen two rays intersect at a point, they form an angle. Angles are usually measured in degrees and ...
Corresponding sides of similar triangles are the sides opposite the corresponding angles. Any segment extending from corresponding angles of similar triangles will have the same proportionality as the side lengths.Similar Triangles Similar triangles are triangles with congruent angles and proportionate side ...
The midpoint of a line segment is the point on the segment that is equidistant (the same distance) from each endpoint. Because a midpoint splits a line segment into two equal halves, the midpoint is said to bisect the line segment. ...

The alternate interior angles are equal. The alternate exterior angles are equal. The pair of interior angles on the same side of the transversal is supplementary. We can say that the lines are parallel if we can verify at least one of the aforementioned conditions. ...
Line segments that have equal lengths are calledcongruent line segments. The point that divides a line segment into two congruent line segments is called themidpointof the line segment. This video explains and demonstrates the fundamental concepts (undefined terms) of geometry: point, line, plane....
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:1. Draw the Cyclic Quadrilateral: - Let PQRS be a cyclic quadrilateral. This
