Area of the isosceles triangle Aria = (b * h) / 2 The area is equal to the base (b) multiplied by the height (h) divided by 2 The height is found by Pythagoras' theorem from the right triangle formed when the height falls perpendicular to the base |

Isosceles triangle: Definition: The isosceles triangle is the triangle that has two congruent (equal) sides, the third side being the base Isosceles triangle, where the side BC is the base of the triangle ABC, and the congruent sides (of equal lengths) are AB and AC: [AB] ≡ [AC] In any isosceles triangle, the height corresponding to the base is bisector, median, mediator and axis of symmetry. Either: ΔABC isosceles with [AB] ≡ [AC] and AD⊥BC, D∈BC => AD bisectors: ∠BAD≡∠CAD; Median AD: [BD] ≡ [CD]; AD mediators for [BC]: AD⊥BC and [BD] ≡ [CD]; AD axis of symmetry: ΔBAD≡ΔCAD. |
