what statements are true about the orthocenter of triangle jkl? check all that apply.

the orthocenter is where the medians of the triangle intersect.
the orthocenter is where the altitudes of the triangle intersect.
the orthocenter will lie on triangle jkl.
without constructing the orthocenter, it is impossible to know if it will be on, in, or outside the triangle.
to find the orthocenter, determine the midpoints of the triangle sides.

Step-by-step explanation:

The orthocenter is where the altitudes meet. Each altitude is orthogonal to the base to which it is drawn, so the prefix ortho- is appropriate for describing their point of intersection.

For a right triangle, the orthocenter is the vertex of the right angle, so lies on the triangle.

step-by-step explanation:

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
