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 ...

Lines and Angles are basic shapes in geometry. Definitions of different types of lines and angles along with their properties are explained here at BYJU'S with examples and video lessons.
An angle between a tangent and a chord through the point of contact is equal to the angle in the alternate segment. The opposite angles of a cyclic quadrilateral are supplementary The exterior angle of a cyclic quadrilateral is equal to the interior opposite angle. ...
Definition of a Line Segment A line segment is a segment of a line, or in other words, we can say that a line segment is a line with two endpoints. For example, The diagram shows a line L and one segment of this line is AB. ...
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...
Therefore, when we draw all the {eq}n - 3 {/eq} diagonals from one fixed vertex, the original polygon is divided into {eq}n - 2 {/eq} triangles. As we are going to see in the next section, the sum of the interior angles in a triangle is equal to {eq}1 8 0^{\circ} {/...
How do you find the corresponding parts of similar triangles? 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...
Irregular Hexagon:This is a hexagon that has sides and angles of different measurements. All the internal angles are not equal to 120°. But, the sum of all interior angles is the same, i.e., 720°. Convex Hexagon:This is a hexagon in which all the interior angles measure less than ...
Example 3.If p and q are two lines parallel to each other and ∠E = 50°, find all the angles in the figure below. Solution: It is given ∠E = 50°. The two lines are parallel → The corresponding angles are equal. Since ∠E and ∠A are corresponding angles, ∠A = 50° . ...
