Always true, sometimes true, never true. 1) the centroid of a triangle is a point where the medians intersect.

2) a line of reflection is also a line of symmetry

3) a figure with rational symmetry can be rotated x degrees about a one of its vertices and the resulting image lines up perfectly with the original image.

4) the centroid of a triangle is located inside the triangle

5) all points on the angle bisector of
6) if there exists a transformation that takes triangle QRS to triangle XYZ then the triangles are congruent

7) the inscribed circle of a triangle intersects all three of the triangles vertices.



TRUE OR FALSE:

8) the base is the length of the altitude

9) a median of a triangle cuts the original triangle into two smaller triangles, each of whose area is half of the original triangle

10) the circumscribed circle lies inside the triangle and touches each of the sides

11) the incenter of a triangle is a point where the angle bisectors intersect

I really need help on these ASAP, thank you!!
