hello :
the center is : (-7 , 9)
Answer:
(22;-3)
Step-by-step explanation:
if to calculate the coordinates of the given midpoint it needed to use:
then to calculate the coordinates of endpoint2, it needed to perform the substitution:
finally:
Vertices of the given triangle are: (0, 0) , (8, 0) and (-6, 0)
If we dilate the triangle with a scale factor of 1/2 , then the new vertices will be...
Now we will just plot those vertices for getting the dilated triangle.

Answer:
Isosceles
Step-by-step explanation:
Consider triangle ABC, BD is the median and the altitude drawn to the side AC. This segment (BD) divide the triangle ABC into two triangles: ABD and CBD.
In these triangles:
- AD=DC (because BD is the median);
- ∠ADB=∠CDB=90° (because BD is the altitude);
- BD is common side.
Thus, by SAS postulate, triangles ABD and CBD are conruent. Congruent triangles have congruent corresponding sides. Hence, AB=CB.
If in triangle ABC, AB=BC, then this triangle is isosceles.
