A kite, showing its pairs of equal-length sides and its inscribed circle. In Euclidean geometry, a kite is a quadrilateral with reflection symmetry across a diagonal. Because of this symmetry, a kite has two equal angles and two pairs of adjacent equal-length sides. Kites are also known as deltoids, [1] but the word deltoid may also refer ...

WebApr 10, 2024 · The circle theorem helps understand the concepts of different elements of the circle, like sectors, tangents, angles, chords, and radius of the ring with proofs. A circle is the joining line of all the points that lie at an equal distance from a fixed focus point. This fixed point is in the middle point inside the circle. WebDetermining tangent lines: angles. Determining tangent lines: lengths. Proof: Segments tangent to circle from outside point are congruent.
