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 ...
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
you may be given the measurement of a mid-segment, which is parallel to both bases and has a length equal to the average of the two bases. Use the given measurements to determine what measurements, if not the angle, can be calculated. These calculated measurements can then be used...

When two angles are joined by one line segment (or ray) and a vertex, those angles are said to be "adjacent angles." Vertical angles are never adjacent, as they share a vertex but not the same ray or line segment. In Figure 1, angles 1 and 2 are not vertical, in that they share...

If two angles on one triangle are congruent in two angles of another triangle, must the third angles of the triangles also be congruent? Why or why not? Given the diagram, which angles would be congruent under the corresponding angles theorem?
Which postulate can be used to prove that the triangles are congruent? If two angles on one triangle are congruent in two angles of another triangle, must the third angles of the triangles also be congruent? Why or why not? What is a theorem for parallel lines cut by a transversal creates...
