The triangles are congruent by SAS theorem
Step-by-step explanation:
For example you can select a right-isosceles triangle with vertices at (0,0), (-4,0) and (-4,4)
Identifying the midpoints of its sides with form a right-isosceles triangle with vertices at (-2,0), (-4,2) and (-2,2)
The second triangle is an isosceles triangle that is half the original triangle
The lengths of the sides of the triangles with vertices at the mid-point is half that of the original triangle.
