WebAn isosceles triangle is a triangle that has two equal sides, regardless of the direction of the apex of the triangle’s points. Since they have two equal sides, they also have two equal angles. In the triangle ABC below, we have AB = AC. Similarly, in the triangle PQR, we have PQ = PR. The vertices A and P are known as the peaks or apices and ... Every isosceles triangle has an axis of symmetry along the perpendicular bisector of its base. The two angles opposite the legs are equal and are always acute, so the classification of the triangle as acute, right, or obtuse depends only on the angle between its two legs. See more In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter … See more Height For any isosceles triangle, the following six line segments coincide: • See more In architecture and design Isosceles triangles commonly appear in architecture as the shapes of gables and pediments See more Long before isosceles triangles were studied by the ancient Greek mathematicians, the practitioners of Ancient Egyptian mathematics and Babylonian mathematics knew how to calculate their area. Problems of this type are included in the See more Euclid defined an isosceles triangle as a triangle with exactly two equal sides, but modern treatments prefer to define isosceles triangles as having at least two equal sides. The … See more For any integer $${\displaystyle n\geq 4}$$, any triangle can be partitioned into $${\displaystyle n}$$ isosceles triangles.
