Anglesare fundamental to our understanding of shapes and how they fit together. While you might have come across acute, right, and obtuse angles, today we will delve deep into the world of reflex angles. They’re not as commonly discussed as the others, but they play a crucial role in va...
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 ...
In geometry, a trapezoid is a quadrilateral (four-sided figure) in which only one pair of opposite sides are parallel. Trapezoids are also known as trapeziums. The parallel sides of a trapezoid are called the bases. The nonparallel sides are called legs. A trapezoid, like a circle, has ...
How to determine the midpoint of each line segment with the given endpoints Does the slant height of a pyramid always bisect the base edge it ends at? Find the value of 90 - 9 + 123456789. True or False: If two corresponding angles of two triangles are proportional, then the two triang...
Let A, B, C, and \(C'\) be four points of a circle \(\mathcal {K}\), where line \(CC'\) lies on another fixed (finite or infinite) point F. Then the locus of two diagonal points (not on line \(CC'\)) of cyclic quadrilateral \(ABCC'\) is a conic if C is moving al...
The burner is mounted on a sliding arm attached to, and pivoting on the axis (R) of a shaft so that the burner can be guided along the segment of a circle with centre-point(S); points (R,S) are situated on either side of the axis of the round bar so that the burner can ...
Arcs and subtended angles are two basic concepts in geometry. An arc is a part of a circle, and a subtended angle is an angle that is created by two points on the arc. These concepts can be used to solve various types of problems related to circles and a
