Question

if the middle point of the base of a triangle is equidistant from its sides prove that the triangle is isosceles​

Answer 1

Step-by-step explanation:

If the point is on the perpendicular bisector of the line segment between the two points, then in the triangle formed by the base being the line segment, and the point being the vertex, the line from the vertex of the triangle to the midpoint of the base is perpendicular to the base, so the triangle is isosceles
