Question

Отрезки МР и МК - перпендикуляры, проведенные из некоторой точки основания ВС равнобедренного треугольника АВС к прямым АС и АВ. Отрезок ВН - высота этого треугольника. Докажите, что МР+МК=ВН.

Answer 2

Proof that MR = MK = VN in an Isosceles Triangle

To prove that MR = MK = VN in an isosceles triangle, we can use the properties of perpendiculars drawn from a point at the base of the triangle to the sides.

Given: - Isosceles triangle ABC with AB = AC - Perpendiculars MR and MK drawn from a point at the base of the triangle to the sides AB and AC, respectively - VN is the height of the triangle

We need to prove that MR = MK = VN.

Proof:

1. MR = MK: - Perpendiculars drawn from the same point to the sides of an isosceles triangle are equal. - Therefore, MR = MK.

2. MK = VN: - In an isosceles triangle, the perpendicular drawn from the vertex to the base bisects the base. - Therefore, MK = VN.

3. Conclusion: - From the above, it is evident that MR = MK = VN in the given isosceles triangle ABC.

Therefore, it has been proven that MR = MK = VN in the given isosceles triangle.
