👉 Learn how to solve with similar triangles. Two triangles are said to be similar if the corresponding angles are congruent (equal). Note that two triangles are similar does not imply that the length ...

Constructions (accurate drawings) can be made using a ruler, a pair of compasses and a pencil. A line which cuts an angle into two equal side angles is called an angle bisector. In geometry a ...

In the diagram below, AB is the chord of a circle with centre O. OM is perpendicular to AB (meet at a right angle). Look at triangles OAM and OBM. The hypotenuses (OA and OB) are the same, as they are ...

The Mathematical Gazette is the original journal of the Mathematical Association and it is now over a century old. Its readership is a mixture of school teachers, college and university lecturers, ...

Description This model of a part of a hinged dissection consists of two triangles hinged at a common vertex. Objects MA.304723.755, MA.304723.760, and MA.304723.804 form model 6TQ (angle bisectors of ...

The four triangular pieces of two models denoted by MA.304723.755 and MA.304723.760 may be arranged to form a parallelogram (in two ways) and a triangle (in two ways), constituting a partially hinged ...
